I noticed a large bright purple and green bruise on the inside of my thigh two weeks ago. I don't remember bumping into anything. The bruising grew larger in that week, but is now finally starting to lighten after two weeks. In the middle of the purple bruise-looking ring there is a bump. It almost feels like there is something inside my leg. It doesn't hurt anymore but doesn't feel or look like a bruise. I thought it may be a spider bite. Is it possible there is a something in my leg like a bug or eggs or something? do these symptoms sound familiar to you.
