Hi: My sphencter has a couple of hard substance and it ended up coming to a white head and I squeezed it and little pimple looking puss came out and the other I squeezed it and made clear fluid come out. I had put preperation H due to some swelling. Now its not swollen but the two pimples are there. What is it and what can I do over the counter remidies?

Summarized question: What causes swollen sphincter?
