It started a few months ago with pressure. Then turned into headaches, i have had no relief. The pain is everyday. Its no longer a headache i would say, but more of sharp pains in head and a constant pressure type feeling. But just recently i started having face tingles, all over body twitches. My muscles twitch all over the place, i also have bone pain in my fngers, and hand/wrist. The back of my head hurts to move when im lying on it, like to turn my head. I also have this weird click noise in my head, usally when walking, or straining. My head pain is worse when i laugh, cough, bend over. My left ear seems to ring alot more, also it seems to get a "clogged feeling" ; Im scared to death its a brain tumor, im convinced it is. Any thoughts? im really worried.
