ANSWER:
Such ‘healers’ are soothsayers and they should be avoided at all costs! Such sacrifices are shirk provided for the jinn and takes a person out of the fold of Islam.
Going to the soothsayer or fortune teller for fun, renders the prayer of an individual unacceptable for 40 days. If one goes there and believes what they say, he nullifies his Islam and is not a Muslim anymore.
If you maintain your daily adhkar, you will be protected from every evil with the grace of Allah.
Do ruqya on water, preferably zamzam and drink lots from it throughout the day and night and also bathe with this water until you’re cured by the will of Allah.
