my child suffered with chicken pox few months later, and now after that he mostly suffer with headache, plz guide ?

A. Very honestly speaking chickenpox has got no connection with headache so you just mixing up two things so I would like to say that headache is very commonly seen with the child is watching too much of the child is not sleeping properly or proper duration at a stretch and lastly there may be a possibility of vision issue so better to check with the doctor for that
