Dear Kurt, problems of the skin is not easy to deal with. This is
something best taken care of by a dermatologist (a doctor who has specialised
in skin problems). You unfortunately did not indicate how long the lump has
been on the exterior of your arm. You also gave no indication whether it is sensitive
to touch or painful. It is not a good idea to squeeze any lump. The mere fact
that some dark blood came out of the lump after you squeezing it, could
indicate that it may be a furuncle or maybe even a boil. Without any additional
information, I would advise that you have it seen to by a health professional. (MCH).
