I need help. I get reoccurring ingrown hair bumps under my arm. I had to have surgery before because it got the size of a nickel and it was fine, but after awhile it keeps reoccurring and healing repeatedly. The last time I went to the doctor she told me it was from ingrown hair, hair growing then going back into the skin causing bumps in my armpits. The doctor told me to exfoliate and keep hair off as often as I can. It keeps coming back, she told me the name of it, it was a long word, but I can't remember. My question is what can I do to prevent these hair bumps from reoccurring. I can't wear sleeveless shirts, swimsuits, she also said that it's a myth that these particular bumps was signs of diabetes. Please help me.
