Very painful. Not an ingrown hair. TMI

First off let me say sorry about all the hair I’m 4 weeks pp and I’m not about to bring a razor down there. Next let me tell you this came about a week or 2 pp and it’s about the size of a quarter under my skin. At first I got l some pus out of it and it was dark yellow greenish with blood . The only thing that makes me say not an ingrown hair is the size and just feel over all, it just doesn’t feel like one to me. It’s pretty painful for what it is. The surface size is way different then the size under the skin.
