I found a lump on the top of my wrist (palm side down) diagonal to the bone. Haven't bumped my wrist, hurt it, or have done anything that could have caused it. It's been there for eleven days and I don't see any difference in size. It feels squishy, kind of like a hard rubber plastic ball when I press on it. I'm scared about what it is and I've looked all over the internet for answers. I don't know what to do.
