Probably not like you. I do the new CurvesSmart and I do light weights at home, and videos and Gazelle etc.
In 2001 I fell backward off some stairs that had no railing, shattered that arm below elbow and I have a pin and a plate there, but this lump is above all that.
It has been there a while, but the arm did not hurt till the last three weeks. First I thought something to do with the injury, but that was so long ago.
I developed rosacea last year and I showed the lump to a dermatologist a few months back and he told me to see a surgeon and have it removed. Then I lost my insurance for now.
So, no, I don't know what it is. It scares me that it didn't hurt for so long and now hurts all the time. The lump itself does not hurt, but the arm hurts when I move it or lift ANYTHING, hurts from elbow down. I guess it is possible that this is two separate things? Maybe the pin or plate broke or moved and that is the pain? But then if that is so, what is the lump? Let me know if you find out anything, please, and I will do the same.
