Hello around a week ago I had this bump form on the left side of my bikini area. It’s hard, red, warm, and painful. At first it was around the size of a dime and as each day kept passing by it kept getting more swollen and red. It hurts when I walk and sit. I thought it would be an ingrown hair or a boil but I don’t see any puss. It’s just swollen and red and even touching it causes pain.
