I have these lumps that are very deep under my skin, you can't see them, only feel them. I've have one in my arm for about 10 years, but I've been getting more and more over this last year. I have one on my lower back, several in my upper leg on both sides, one on both of my arms, etc. They are pretty firm, not painful, just occasionally itchy.
I was just wondering if anyone knew what these might be and whether it was worth bothering the GP about it. I have only thought about going to the GP about them because recently they have been more itchy than normal.
