Hi- a few weeks ago I had a red and inflamed ingrown hair that got infected after being around for over 6 months. I got a penicillin shot, antibiotics, and a 2nd shot of penicillin. It went down, no more redness or swelling. Well out of nowhere it’s back, huge and red and swollen, a little painful (see photo.) I have an appt Friday to see dermatologist again. Any advice? I’m scared and never had this happen before. At what point do I go to ER?
