Basically the only thing wrong with me is that I get head pain whenever I stand up or when I sneeze, clench my teeth, or anything else similar. I suspected high blood pressure but I went to the doctor and it was 120/75. The doctor suggested it was from overexertion because I was on vacation in the New England area and did a lot of walking which I'm not used to and possibly a cold virus as well. I was told to take normal doses of Advil, which I did. I was also told it should be gone in a couple of days, but that time has elapsed and it has actually gotten worse when the Advil wears off. Any thoughts?
