Double headed boil on my back, went to urgent care as it was super angery/ infected and earliest appointment with my derm was February. They lacerated it and drained it. 2 weeks of 2 antibiotics only to realize they didn't even take out the sack. Guess
What is this on my arm? The skin around is rough, and it's the fifth time I've had to pop it. I have keratosis on my arms but have seen nothing like this before
