I just got another one. It was really really really swollen yesterday (though it was relatively fine after my ride on Sunday). I did an epsom salts compress today to get it to drain some, which cut down on the pain a lot. My derm gave me a prescription for Zithromax. I've put off taking it, hoping it would just resolve itself on its own. It's turning into being like one I had in the same spot that lasted for a LONG time, so I guess I'm going to try the antibiotics and see how that goes...
