I am down 35lbs since I was banded 4 weeks ago today but I am still having some pretty serious pain in my left shoulder. Could that still be related to the CO2? I sometimes have it when I feel gassy in my stomach. The dr's office thinks I could still be eating to fast but I am very cognizant of how many chews I need before I swallow. Has anyone had the pain for this long? I have a very high pain tolerance but if this doesn't stop in a couple of weeks then I am getting this thing out of me. Thanks in advance!!!
