Okay well my b/f has been complaining about pains in his stomach for a while now I would say 2 months or so. He complains of bad stomach akes, gas, tingling in his hands and arms, and some vomiting. I dunno what it is. He doesn't like going to the doctor but he went like 2 weeks ago to the doctor and he just took blood from his arm and stomach and said it might be something with his kidneys, but today he saw a bump on his stomach and he doesn't know what it is. I was just wondering what can it be? Can somebody help?
