Re: Lump found on outside area of upper arm
First, do not panic. Next, check the other arm to see if there is one in the same spot on the other side. Next, if it is painful, itching or is gathering fluid, see your doctor. There are many things it can be. Lipoma- fatty tumor(even if you are overall skinny) a bug bite, a blood vessel, a place where you bumped yourself and forgot about it. If it is still there and you are still scared see your doctor.
