I've been experiencing some very wierd symptoms over the past 6-8 months. These symptoms include dizzyness, dry mouth, digestive problems, constipation, loose bowels, muscel twitching, insomnia, and I fainted yesterday. I am only 24 years old. I've seen a lot of doctors and been to alot of emergency rooms my sugar level came back normal. However, I am looking for some ideas as to what I should ask to be to be tested for-seeing as how I know when something is wrong with my body and I am very concerned. :(
