Over the past few weeks I have developed small bumps all over my arms, legs, face, and chest. I developed a small patch on my lower back that was extremely itchy, and the bumps grew (I suppose I was itching in my sleep!) and then scabbed over. Some dried and fell off after a couple weeks, but one just stayed...for nearly a month! I got tired of it and tried to scratch it off. It was so deep I had to use tweezers to pull it out. I couldn't even feel it happening, but it took about 10 minutes it was so hard to pull. I didn't even get all of it and it still doesn't hurt. It is a red dot in the middle, surrounded by a discolored patch, and then a red circle around. Now I am developing another patch on my arm. What is going on!!! Please help!
