about once a week I have gotten what looked like a pimple in random places on my body one on my arm just above my wrist and 2 weeks ago there was one where my arm bends on other side of elbow, they both started looking like a pimple but when popped they get a red ring around the hole that swells and hurts like its bruised also area seems hot and a lump under the skin still there. Ive had one on my leg as well about a month ago.
