<s>[INST] Today at work, I experienced some sudden sharp local pain in my right breast. When I got home, I remove my bra and had a lump appearing to be like a pimple with smaller bumps off to the side. I put some tree tea oil on it and it has cleared up somewhat. The pain has lessened, but that is probably because of the ibuprofen. [/INST] it is due to minor trauma/infection of the hair follicles and not to worry much!apply ice-cubes / ice packs and see!all the best! </s>
