I have large abcesess on my upper inner thighs, and in my pubic area. Some are tender to touch some are not.. they also never form a head, They are not filled with puss, when they open up they are only filled with a redish oily liquid. I have had them a long time. they will go away for a awhile after draining, leaving these dark red spots. Then returning, a few weeks later. I am 24 and 260 pounds. What are they and what can I do to solve my problem?
