Hi. How long has this been going on and any redness or tenderness?
What did the nurse have to say?
Can be very tender at times, no redness.Nurse said if it was painful there was no problem.
Well Robert since it's tender this is probably mastitis--an infection of your breast tissue.
That said, men can get breast cancer just like women, so you need to have a doctor examine this and get a mammogram to see if it may be mastitis, a cyst, or even cancer even though that's unlikely.
With mastitis, a course of antibiotics usually resolves that
Let me know if you nee more information please
