I had severe compression of spine in T6-T9, I had an open thoracotomy last Jan. and had a discectomy and partial vertabraectomy with a rod placed. The surgery was done on the left side. I have had severe pain and been taking gabapentin and nortriptyline and codine for neurapathy. My left breast has been swollen since the surgery. It is still about a size larger than my right breast. I was perfectly uniform before the surgery. I was wondering if the breast swelling is normal. Is it from the medications or from the surgery?
