I am a 36 year old male with an inflamed left nipple with a red ring around it. It is very painful. Problem is ongoing for 2 days now.  I recently spent most of a day in a life jacket which is the only cause of irritation I can think of, but Im not sure that is really the problem, as the irritation didnt begin until about two days later.
Hii.welcome to our site.I have gone through your question. The redness may be due to inflammation. Apply fusiform ointment twice daily on the area for 7 days. Take ibuprofen tablets twice daily for 7 days for pain. You can apply cold compressions on that area.don't squeeze the lesion.thank you.
