Hello ,I am a 33 year old male. I recently discovered a harder lump about the size of a quarter on my stomach, just below the rib cage. It is kind of a purple color. It is somewhat painful when u touch it, but I don t really feel it during the day , and it doesn t bother me. I thought it was possibly an ingrown hair, but I cannot see any hair follicle, and I have had this for about three weeks. I m not sure what it is and I m not sure how to treat it. Thank you
