Hi, yesrerday I found a pea sized lump under my skin on upper arm. The other one is clear. I have to bend the arm in the elbow and touch in the deep otherwise I cant feel it..but I found it:-( when I was scratching..is it normal? Is any kind of muscle stuff? Anyone else have it,guys? Thanx!!

It is on the lower (back) side of left upper arm

It's probably just normal muscle gristle, I just posted about a lump after a bruise under my skin. Might have been there years after you bumped it maybe? See if a nurse / doctor can have a feel but doesn't sound like anything bad :) x

My arms are so lumpy I think it’s fat or muscle gristle as said above they’re like tiny lumps I can pick up with my fingers and they move
