I'm having sharp pain in my head sometimes at side of my head sometimes at the center of the head. While standing and walking I am having such pain. For few seconds I can't do any thing. I am having heaviness in head as well as vomiting sensation too. I have sinus and ear problem also. I took treatment for sinusitis but still having same problem. Feeling so sick and having breathing problem also. Please clarify my problem. Am having thyroid also.
