Earlier last week I noticed I had some pain on my bikini line and didn't think much of it until I noticed a marble sized mass nearly an inch under the skin on my upper thigh near the buttocks..I'm not sure if its an ingrown hair or acne or an infection. I am worried a bit because of how deep it is and hasn't changed in nearly a week. If anyone has any ideas and how to get rid of it, instead of going to the doctor considering the location of the mass, that would be awesome.
