So I had noticed a while back that I had a lump or two on the skin of my shoulders. Both of them. They all look slightly different. One is solid and not raised. While all of the others are raised and pink/skin colored. Then I got a sore that healed and turned into a lump too. I have I think 10 lumps on my shoulders all together my mom says they are probably cysts. Should I get these checked out? And since there are 10, does that mean that if this is something bad that it has spread and is very bad now?
