Lately I have been feeling CONSTANTLY hungry. I know this may be a sign of diabetes but I have not exhibited any other signs, i have not lost any wieght, probably gained it in fact, i am not urinating more, i d not feel thirsty all the time, and I actually have problems sleeping most of the time. I have however broken out in a rather odd rash, it only shows up sometimes and it itches like crazy, it is just a patch of red bumps that goes away within a few hours. Do you have any ideas as to what might be wrong with me?
