If you have a severe headache ask someone to hold your head in his hands and he should read Surah fiil without bismillah …for 7 times and do dam (blow) on your head.

If the headache goes away fine if not read Surah Feel 7 times again and do a dam (blow)…..and do it again if the head ache does not go away. Keep on doing until it goes away.

Remember do not read Bismillah with the Surah.
