In 1995 I had a mastectomy and reconstruction with a saline implant of my left breast. Lately, when I'm exercising or using my left arm I get a sharp pain, upper arm. The pain will reduce to soreness in the same general area and implanted breast. After an hour the episode is over. This doesn't happen every day. And, indigestion (burping) seems to accompany the pain. Most of my lymph nodes were removed. Is this pain related to my implant?
