Hi, My son he is now 5.5 years old. Often he says his back head aches may be in a month twice or thrice. (When we ask him to read and write or when very strict with him this happens so far we noticed )When this happens he want to take lie down and once sleep and get up he does not have back head pain. Can you please suggest what we have to do now. Some time in a month he does not get head ache at all.
