I Wonder What's Going On.

Seems ever since I had surgery I've been finding lumps in different places. They have all been checked and cleared. Now I have 2 more lumps in my head to be checked. I'm not sure if that is from having the nodes removed from under my arm and the fluid is just getting stuck on my left side or if it is something different. Biopsys are not nice and I have had loads of them already. Does it ever actually end or do I have to keep stressing about finding lumps.
