I have a small lump under the skin, it's the size of a jelly bean. It is a bluish purple color. It has moved about 4 inch up my arm in a couple days?

It's possible u have a hematoma there and some blood may have tracked up your arm. Do u remember any injury to the site? Does it hurt to touch? Did anyone grab you? An enlarged vein (varicose) might appear like this too. Hope u can get some relief. ...Read more
