You need to see the Dr. It can be nothing, or it could be something and the sooner you find out what it is, the better. I had a huge lump in my forearm and finally made it in to the Dr. Where my lump is, there are not lymph nodes nearby. I have a fatty tumor, like dogs get. Don’t laugh, they’re actually very common. It’s gone down a lot since then.

Please get it checked out. Is it sore at all?
