Boil: Get to a doctor, asap> sounds like it could be infected and may need to be drained. The drainage procedure will make you feel better almost instantly.

Boils: A boil is a localized collection of pus and bacteria. This requires drainage and, often, antibiotics. As staph is extremely common, delay in treatment is not recommended. A simple procedure (incision and drainage) can be performed to remove the collection of pus and antibiotics is usually started by mouth. I would not recommend seeking treatment by a dermatologist, an urgent care center, or gp.

Boil?: A boil is a localized skin infection which should be red, hot, swollen and tender. Also, it should feel hard unless it is a localized abscess and has pus. If so, it is unlikely it would be present for a month without change. Other considerations are a benign fatty mass called lipoma or a bruise in the area from trauma from your panty elastic. Regardless, a doc visit is a good idea to find out.
