Hi there, I have been finding these large, raised, bite-like bumps on my legs, hips, and back. They are not itchy, only sensitive to the touch. The first two pictures are of the two oldest bumps, about 3 weeks old. The last one, on the back of my leg, is around 2 weeks. They are all very large, and in the middle of the raised bump there appears to be a large chunk of meat taken out.
