My would-be is 24 yrs old, and hard worker in her home. She has a problem, the problem is feeling pain on back head during the time of work. Especially those works which is used by her hand, applying forces means hard push or pull, picking weights from floors, or from a little high, washing clothes, cleaning etc. In these times she feel pain on her back head. She also a thyroid patient using thyronorm 50 tablets. Why it is happening, is it a neuro problem? I need a reply.
