My friend has goton bumps underneath the skin, you can wiggle it around. There about the size and shape of a Lima bean and feels like the cartilage in your ear. He has about 15. all over but mainly on forearms. His joints feel weak, tired more ofton than should be, wants to sit down allot cannot stand in one spot long. Does not have to sit feels like he wants to and hurts more than should. The reason i am asking is because he does not want to get it checked out.
