Pain on right side by ribs and into back. been nauseated. been a couple of months. woke up this morning & my legs and arms are aching. what is this?

You need 2c your MD: Difficult to pinpoint. Your symptoms are pretty non specific. The best advice I can give you is to see your primary MD about this. The symptoms may not be related to one another but that's what a good doc does, takes a thorough history and physical exam. Then you should have more direction about all this. Best wishes to you!
