am 23 years old and a bit concerned. On Wednesday night I experienced 2 hours of irregular (fast, skippy) heartbeat. It has continued occassionaly but not for any significant amount of time. I then noticed on Friday that my right breast, along the right side, was sore. Upon self- examination I noticed a sore lump. It is now Tuesday and it continues to be sore and now can easily be felt through clothes. It feels like a gumdrop, doesn't move, is slightly smaller than a golf ball and shaped like a figure eight or a circus peanut. I have noticed a smaller one above it and a larger one on my LEFT breast now above the nipple. So now three Very painful lumps that are big enough to be easily detected through clothing. I normally have tenderness in both breast before my period but never anything like this. All else seems normal. I have no health insurance. Whats my next step?
