I had a baby 3 months ago and nursed him for 2 months when I began symptoms of a blocked milk duct in the left breast. I stopped nursing and still a month later I have a stinging pain that radiates into the armpit. No palpable lumps felt so I went to my primary who gave me abx for possible mastitis. no change in the pain so went for us. Radioligy says left breast is clear but the right showed a 1 to 2 mm nodule that looks benign. Now Im confused. Im trying to find answers to the pain on the left and turn up with something on the right. The radiologist did not recommend a biopsy nor a mammogram. Im going to have one anyway but is it wise to wait 6 months and repeat the us. this was the recommendation. I thought the pain was related to the breastfeeding but I just dont know anymore. The nodule is located at 9 o'clock on the right but it was not felt by me or my doctor. Should I have a biopsy even though its not recommended and how will I get an answer as to the left side pain.
