Generally there are 2 steps involved in treatment. Firstly diagnosing the problem or cause ie, checking for symptoms and then the second step follows i.e., treating accordingly. Many Raaqis (Raaqi means a person who does Ruqyah i.e., reciting Qur’aan and du’aa’s over the sick for the purpose of seeking healing) offer different Ruqyah treatment programmes, they will be according to Qur'an and sunnah - they just differ in their recommendations. So long as a Ruqyah treatment programme is free of shirk they are okay to differ in their recommended sunnah treatments e.g. one may say recite Surah fatiha7 times, others may say 3times, both are fine. Some may use Olive oil, while other Raaqi may use Honey or Kalonji Oil.
They will often ask, the following pieces of information: who requires the Ruqyah, what the symptoms are, brief detail of events, they will then arrange an appointmentwhich may usuallybe for an hour or less depends on the raaqi you are contacting.You may be given some advice before you come to the appointment, for example: bringing a large bottle of water/olive oil with you so that the raaqi is able to recite upon them. During the treatment, the raaqi will begin reciting, often into the persotn’s right ear. These will (and should) only be aayaath of the Qur’an and duas from sunnah.There may be other differences such as using a microphone/not using a microphone, sprinkling ruqya water on the person/or not etc. A sister patient should not come alone but with a relative and should be in hijab completely for treatment. 
The use of an agent, procedure, or regimen, such as a drug, surgery, or exercise, in an attempt to cure ormitigate a disease, condition, or injury. Or The manner in which someone behaves towards or deals with someone or something. 
The term ‘Raaqi’ is used for an Islamic ‘Spiritual healer’ or exorcist and refers to someone who has knowledge of Islam, of Ruqyah treatment through education and experience, and performs ruqyah treatment for individuals with ailments who are unable to perform ruqyah upon themselves (self ruqyah). A person may not be able to perform Ruqyah on themselves if they are severely unwell or do not have sufficient knowledge or understanding of their ailment.
1. Self-Treatment - There is nothing wrong with the Muslim reciting Ruqyah for himself. That is permissible; indeed it is a good Sunnah, for the Messenger (ﷺ) recited ruqyah for himself, and some of his companions recited Ruqyah for themselves.
Proof:It was narrated that ‘Aa’ishah (may Allaah be pleased with her) said: When the Messenger of Allaah (ﷺ) was ill, he would recite al-Mu’wazatayn (Surah 113, 114) over himself and spit drily. When his pain grew intense, I recited over him and wiped him with his own hand, seeking its barakah (blessing).” Sahih al-Bukhari, 4728; Sahih Muslim, 2192
2. Treatment by others - With regard to the du’aa’ that is prescribed for the Muslim to say if he wants to recite ruqyah for himself or for someone else, there are many such du’aa’s, the greatest of which are al-Faatihah and al-Mu’wazatayn.
Proof:A group of the Companions of the Prophet (ﷺ) set out on a journey and travelled until they made came near one of the Arab tribes. They asked them for hospitality but they refused to do so. Then the leader of that tribe was stung, and they tried everything but nothing helped him. Then some of them said, Why don’t you go to those people who are staying (nearby)? Maybe some of them have something. So they went to them and said, O people, our leader has been stung and we have tried everything and nothing helped him. Do any of you have something? One of them said, Yes, by Allaah. I will perform ruqyah for him, but by Allaah we asked you for hospitality and you did not give us anything, so we will not perform ruqyah for you unless you give us something in return. So they agreed on a flock of sheep, then he started to blow on him and recite Al-hamduLillaahiRabbil-‘Aalameen. Then he recovered quickly from his complaint and started walking, and there was nothing wrong with him. Then they have them what they had agreed to, and some of them (the Sahaabah) said, Let us share it out. The one who had performed ruqyah said, Do not do anything until we come to the Prophet (ﷺ) and tell him what happened, and we will wait and see what he tells us to do. So they came to the Messenger of Allaah (ﷺ) and told him what had happened. He said, “How did you know that it is a ruqyah?” Then he said, “You did the right thing. Share them out, and give me a share.” And the Messenger of Allaah (ﷺ) smiled.Sahih al-Bukhari, 2276, and Sahih Muslim, 2201
It was narrated that ‘Aa’ishah (may Allaah be pleased with her) said: When the Messenger of Allaah (ﷺ) was ill, he would recite al-Mi’wazatayn over himself and spit drily. When his pain grew intense, I recited over him and wiped him with his own hand, seeking its barakah (blessing).” Sahihal-Bukhari, 4728; SahihMuslim, 2192
Ibn ‘Abbaas (may Allaah be pleased with him) said: The Prophet (ﷺ) used to seek refuge for al-Hasan and al-Husayn, and he would say: “Your father [ Meaning:Ibraaheemm peace be upon him] used to seek refuge with Allaah for Ismaa’eel and Ishaaq with these words: 'U'eezu bikalimaatil-laahit-taammati min kulli shaytaanin wa haammatin, wa min kulli 'aynin laammah. (Read this 1 time)(Meaning: I seek refuge in the perfect words of Allaah, from every devil and every poisonous reptile, and from every evil eye).’” Sahih al-Bukhari, 3191 
There are some important conditions that must be satisfied in a Ruqyah to make it permissible.They were summarized by Hafiz IbnHajar (May Allah have mercy on him)- There is a consensus among the 'ulama that Ruqyah are permissible when they satisfy three conditions:
They either consist of specific portions of the Quran, such as Surah al-Fatiha or Ayatul-Kursiy, or contain a praise of Allah and an invocation of His help and protection.
'Aishah (May Allah be pleased with her) reported that Allah's Messenger (ﷺ) came into her house and saw with her a woman who was treating her with ruqyah. He told her: 'Treat her (only) with Allah's Book.' Recorded by IbnHibban; verified to be authentic by al-Albani in as-Sahihah no. 1931.
Abu Sa'id Al-Khudri (May Allah be pleased with him) reported: Jibril (Gabriel) came to the Prophet (ﷺ) and said: "O Muhammad (ﷺ)! Do you feel sick?" He (ﷺ) said, "Yes." Jibril supplicated thus (i.e., he performed Ruqyah): "Bismillahi arqika, min kullishay'iny u'zika, min sharri kulli nafsin aw'ayni hasidi, Allahu yashfika, bismillahi arqika. [Meaning: With the Name of Allah. I recite over you (to cleanse you) from all that troubles you, and from every harmful mischief and from the evil of the eyes of an envier. Allah will cure you; and with the Name of Allah, I recite over you]." Sahih Muslim 2186
2. Must Be with Clearly Understood Words
3. Believing That the True Benefit Is from Allah
Example1: You can recite ruqya on yourself by gathering the palms of your hands and reciting in them the ruqya and then blow in your hands and wipe the area that is ill and hurting you.
You can take bring zamzam water preferably and recite 3, 5 or 7 times the following over it and blow every time you recite it:Al Fatiha, ayatulKursi, the last 2 aayaath of SuratulBaqarah and the last 3 Surah of the Quran (Surah – Ikhlaas, Falaq and Naas). You can add to that any Prophetic Dua’a and blow on it.
Drink from this water in the morning, in the afternoon and before going to bed and also you can wipe with it over the places that hurt you. 
Example2:Treatment of Magic after it has occurred.
Ruqyah Ash-Shar'eeyah- from among them are:
Example 3: If the person who causes the evil eye is known, command him to make ablution (wudu) and then the afflicted person should shower with the water from the ablution. (Sunan Abu Dawud 419).
Ayat al Kursy (ayah 255, surah Al Baqarah)
Treatment for Magic or Sihr
Reciting Quran, for it has a great effect in removing (the effects of) sihr. Ayat al-Kursiy, the ayahs (statements) of sihr from Surat al-A’raf, SuratYoonus and Surat Ta-Ha, Surat al-Kafirun, Surat al-Ikhlas and al-Mu’awwazatayn should be recited over the person who has been affected by sihr, or into a vessel. Dua should be made for healing and good health; in particular the du’a which has been narrated from the Prophet (peace and blessings of Allah be upon him):
“Allahumma Rabb al-Nas, azhib al-bas washfi, anta al-Shafiy, la shifa illa shifauka, shifaan la yughadirusaqama”(O Allah, Lord of mankind, remove the evil and grant healing, for You are the Healer. There is no healing except Your healing, which does not leave any sickness).”
One may also recite the words used by Jibreel (peace be upon him) when he treated the Prophet (peace and blessings of Allah be upon him) with ruqyah:
“Bismillahi arqeek, min kulli shay in yuzeek, wa min sharrikulli nafsin aw ‘aynin hasidin Allah yashfeek, bismillahi arqeek (Meaning: In the name of Allah I perform ruqyah for you, from everything that is harming you, from the evil of every soul or envious eye may Allah heal you, in the name of Allah I perform ruqyah for you).”
This should be repeated three times, as should the recitation of “QulHuwa AllahAhad” and al-Mu’awwazatayn.
He may also recite the above into water, some of which should be drunk by the person who has been affected by sihr, and he should wash with the rest, one or more times as needed. This will remove the sihr by Allah’s leave. This was mentioned by the scholars (may Allah have mercy on them), and by Shaykh ‘Abd al-Rahman ibnHasan (may Allah have mercy on him) in Fath al-Majeed Sharh Kitab al-Tawheed, in (the chapter entitled) Bab Ma ja a fi’l-Nushrah, and by others.
One can take seven green lotus leaves, grind them up, and put them into water, then recite into it the ayahs and surahs (verses and chapters) mentioned above, and the du’as. Then he can drink some and wash with the rest. This is also useful for treating a man who is being kept from having intercourse with his wife. Seven green lotus leaves should be placed in water, the verses referred to above should be recited into it, then he should drink from it and wash with it. This is beneficial, by Allah’s leave.
The aayaath which should be recited into the water and the lotus leaves for those who have been affected by sihr and the one who is being prevented from having intercourse with his wife because of sihr are as follows:
1- Surat al-Fatihah
2- Ayat al-Kursiy from Surat al-Baqarah, which is as follows (interpretation of the meaning):“Allah! La ilaha illa Huwa (none has the right to be worshipped but He), Al-Hayyul-Qayyum (the Ever Living, the One Who sustains and protects all that exists). Neither slumber nor sleep overtakes Him. To Him belongs whatever is in the heavens and whatever is on the earth. Who is he that can intercede with Him except with His Permission? He knows what happens to them (His creatures) in this world, and what will happen to them in the Hereafter. And they will never encompass anything of His Knowledge except that which He wills. His Kursiy extends over the heavens and the earth, and He feels no fatigue in guarding and preserving them. And He is the Most High, the Most Great.” Quran Surah 2:255
3- The aayaath from Surat al-A’araf, which are as follows:
“[Pharaoh] said: ‘If you have come with a sign, show it forth, if you are one of those who tell the truth.’
Then [Musa] threw his stick and behold! it was a serpent, manifest!
And he drew out his hand, and behold! It was white (with radiance) for the beholders.
The chiefs of the people of Pharaoh said: ‘This is indeed a well-versed sorcerer;
He wants to get you out of your land, so what do you advise?’
They said: ‘Put him and his brother off (for a time), and send callers to the cities to collect —
That they bring to you all well-versed sorcerers.’
And so the sorcerers came to Pharaoh. They said: ‘Indeed there will be a (good) reward for us if we are the victors.’
He said: ‘Yes, and moreover you will (in that case) be of the nearest (to me).’
They said: ‘O Musa! Either you throw (first), or shall we have the (first) throw?’
He [Musa] said: ‘Throw you (first).’ So when they threw, they bewitched the eyes of the people, and struck terror into them, and they displayed a great magic.
And We revealed to Musa (saying): ‘Throw your stick,’ and behold! It swallowed up straight away all the falsehood which they showed.
Thus truth was confirmed, and all that they did was made of no effect.
So they were defeated there and returned disgraced.
And the sorcerer’s fell down prostrate.
They said: ‘We believe in the Lord of the ‘Alameen (mankind, jinn and all that exists).
The Lord of Musa and Harun.’ Quran Surah 7:106-122
4- The aayaath from Surah Yoonus, which are as follows:
“And Pharaoh said: ‘Bring me every well-versed sorcerer.’
And when the sorcerers came, Musa said to them: ‘Cast down what you want to cast!’
Then when they had cast down, Musa said: ‘What you have brought is sorcery, Allah will surely make it of no effect. Verily, Allah does not set right the work of Al-Mufsidoon (corrupters).
And Allah will establish and make apparent the truth by His Words, however much the Mujrimun (criminals) may hate (it).’Quran Surah 10:79-82
5- The ayaath from Surat Ta-Ha, which are as follows:
“They said: ‘O Musa! Either you throw first or we be the first to throw?’
[Musa] said: ‘Nay, throw you (first)!’ Then behold! their ropes and their sticks, by their magic, appeared to him as though they moved fast.
So Musa conceived fear in himself.
We (Allah) said: ‘Fear not! Surely, you will have the upper hand.
And throw that which is in your right hand! It will swallow up that which they have made. That which they have made is only a magician’s trick, and the magician will never be successful, to whatever amount (of skill) he may attain’” Quran Surah 20:65-69
6- Surat al-Kaafirun
7- Surat al-Ikhlas and al-Mu’awwazatayn (i.e., Surat al-Falaq and Surat al-Nas) – to be recited three times.
8- Reciting some of the du’as prescribed in sharee’ah, such as:
“Allaahumma Rabb an-Nas, azhibal- baswa’shfi, anta -Shafiy, la shifa illa shifa uka, shifaan la yughadiru saqaman (O Allah, Lord of mankind, remove the evil and grant healing, for You are the Healer. There is no healing except Your healing, which does not leave any sickness).”
If the above verses etc. are recited directly over the person who has been affected by sihr, then the reciter blows on his head and chest, these are also among the means of healing, by Allah’s leave, as stated above.Majmoo’ Fataawawa Maqaalaat Mutanawwi’ah li Samaahat al-ShaykhibnBaaz , vol. 8, p. 144
