Thrombosed hemorrhoi: Sounds like you have a thrombosed hemorrhoid. The best thing to do is soak in a warm bath a few times a day and the pain and swelling will subside in a few days. Make sure you avoid getting constipated by adding fiber to your diet. If the pain is just unbearable, see a colon and rectal surgeon who can excise the hemorrhoid to help speed up the process. Creams and lotions are a waste of money.
