I see a lump on my upper arm more when i turn it elbow facing down palm up. in the past i was told its a lipoma now shooting arm pain what's next help?

Doc, check it again: Shooting pain down the arm is the focus of what needs to be evaluated. It may relate to the lipoma. A lipoma, collections of fatty tissue under the skin, may occur in multiple areas of skin. If it changes size, or quality or becomes tender, it should be removed, because there may be a cancerous change in some cells. Shoot pain down arm and lipoma may be distinct problems, have both checked out.

Have it removed: If you have a subcutaneous mass and it hurts, have it removed. See your surgeon.
