I KNOW I should just accept what my doctor says. He says the hard, flat, deep under the skin lump in my arm feels like a cyst to him, and only worry/come back if it gets bigger. It doesn't feel like any cyst I've ever felt before. I know I should just take his word for it but it really feels like the nodes I had from my scalp eczema. So I'm worried that he's wrong and it's cancer and I'm doomed. I know I should just take his word for it, but I just can't stop worrying. I hate this. I thought I was getting better, and now I'm back to not being able to tell if I have a legitimate concern or it's just my brain screwing with me.
