A red boil on left vagina lip has appeared out of nowhere. have been given amoxicillin and am using bacterial cream- painful when i walk or pee. help ?

Boil: This boil may need incised and drained if its not responding to antibiotics. I know it sounds harsh but this would definitely relieve the pain. You should go to the nearest ER or urgent care center.

Vaseline should help: Try applying Vaseline (petroleum jelly) to the painful area to prevent pain with urination. If the amoxicillin and cream were prescribed for this problem, you should continue those for 3-4 days prior to changing these medications. If the antibiotic cream was OTC, you might get better results with Neosporin Plus which contains a numbing agent.

Not "boiled over"?: First of all, condolences on the pain of a boil in a most sensitive location. Unfortunately, you will have to wait for the medication to exercise its' "authority" over the boil and eventually it will dissipate or burst. Meanwhile, try sitting in a tub of hot water to help the process and ease the pain and if it doesn't get better in 3 days go back to your MD who is treating you to have it "lanced"
