Breast Burning

Patient: I have been experiencing a burning sensation in my breast and under my arm. I recently took an allergy medication over the counter. I have been bitten by what I believe to be a spider about 4 different times with two of the bites occurring at the time. Not sure if any of this has anything to do with the burning sensation. Also,I only eat fish no other type of meats. I began this about 1 year ago.
