So about a month or so ago I noticed a throbbing pain
where my left
breast ends, about 5 inches down from my arm pit.It comes and goes
, and had gradually gotten a bit more noticeable. It will last a few seconds, then stop, then last a few seconds, then stop.... Sometimes I go days without having it, other times I will have it every few minutes all day. Breathing deeply and exhaling can make it worse sometimes and sometimes changing my position can make it feel better.
