Should not be embarrassing at all Rani. A few years ago I had tenderness in my left side and could feel a knot or lump. So I went to my family doctor and she sent me forward for a mammogram myself. Told me that is was not all that uncommon for men to get a lump. Imagine My embarrassment, sitting in the waiting room with all women waiting to get their mammograms. I got some weird looks alright. In my case is was just some kind of infection or inflammation. They gave me some antibiotics and it went away. Please get checked out as soon as you can, and don't worry too much about it. Remember we all care for you a lot and are here for you.
