For two days straight, my right forearm up to my hand and wrist has ached. It feels internal, like a deep bone ache (not like how it feels when after exercise), and the position of my arm doesn't matter. It comes and goes, and I don't feel it as much if I'm concentrating on something else, but it's really bad and I'm always thinking about it. I've tried taking lots of Advil and it doesn't do anything. I'm worried there is something wrong with my bone, like a cancer. If it helps, I have felt similar aches in other limbs before, but never nearly this bad, always for only a few hours, and it always went away with pain medication. Thanks so much.
