I have had and still have several painful pimples on my chin . I also have a couple of knots under my chin in that soft area that are sore. The pimples are not normal pimples. They get really big, swollen and then have a thick white discharge . I am prone to breakouts, but these are different. I try to keep my hands of them, but as some get better more show up. I also have several ingrown hairs/pimples around my hairline. I am prone to bumps on the back of my arms and thighs, now those are larger and more sore than normal as well. I ve made sure to wash my face regularly and am only wearing makeup on the rare occasion that I leave the house. What is this?
