Over the last 4 months, I ve had a weird discoloration on my stomach . On the right side, over the course of said four months, I ve had no actual stomach issues, up until recently. I get random really sharp pains that last for hours in my abdomen . The discoloration has me more concerned than the pain, it looks like a light bruise , but the fact that it s been there for 4-5 months now, has me pretty concerned.
