question: I am a 32year old female, I weigh 120lbs. I was seen 4yrs ago because of a discoloration(appeared to be broken blood vessels) they did a biopsy and found it to be nothing. The broken blood vessels went away and I had no problems until a few weeks ago my left arm went numb and when I rubbed it I noticed a hard lump the size of a gumball. It does not really bother me, I gave it a few weeks to see if it would go away...still no change
