I have red swollen painful spots that appear on my inner thighs, around my waist, under my arms, and on my groin. When I pop them it drains bloody pus and leaves a hole in the center. I never had them until I discovered I had pcos and gained weight. I don't know how to get rid of them. I put triple antibiotic ointment on them, clean them with alcohol, I have even poured a bottle of peroxide in my bath water. Nothing helps. They are extremely painful. When I first started my metformin they started to get better, but the metformin makes me sick so I can't take it. What are these spots and how do I get rid of them for good?
