The other night I was getting burning and shooting pains in my left breast and thought maybe it was just a side effect of hormones that I am on. Then after 2 hours of sharp, burning pains I looked at it and it was an open blood blister that was oozing blood. No pus, just blood. It is about the size of a dime and it worried me because it just appeared suddenly. It is about 1.5 inches to the left of my areola. It is not near the wire of the bra. I also noticed a series of bumps all over both breasts that I previously thought were just pimples but now I noticed that they are more red than pussy. I do have large breasts and I thought they were just from sweating during workouts. Is it just a simple blood blister or should I go to the doctor?
