Right now I am absolutely convinced I have soft tissue sarcoma. I have a bumpy lump on my inner left shin just a bit under my knee cap. It isn't noticeable and I noticed it while putting on lotion. It hurts because I've been poking it so much. It's about the size of a grape or a little bigger. I went to the doctor today to have her check it out and she sorta just gently rubbed her hand over it a few times and said it isn't anything to worry about..but I've read so many things on google about soft tissue sarcomas being hard to diagnose because they can be hard or soft. I'm so scared.
