Hello, I used my husband's razor to touch up my armpits 3 days ago (dry). Later that evening, I could feel a pain in that area and assumed it was an ingrown hair. Though no lump was visible, I could feel one beneath the skin.
The next day the lump turned red and had a line that bisected it (not to sound graphic, but it resembled a woman's vagina.) My armpit became extremely painful and the pain has persisted and elevated since then. I have not noticed much of a change in the appearance of the lump, either.
I am wondering if this sounds like a severe case of razor burn, or is perhaps an infection, or maybe some other ailment that I did not think of. Also, what would be a good treatment? Thank you so much!
