I had gastric band surgery 2 weeks ago. I have pain between my breasts and find I have to burp to try and relieve it, the pain goes through to my back. This is so uncomfortable and painful. I tried to make myself sick to feel better and all that did was bring up more air. Can someone please help me with this as I am going round the bend. I had an adjustment in the 2nd week as I had this pain previously. I can't afford $160 a visit to the surgeon every time this happens.
