Got banded 9/9 and have no problems. My port pinches a bit every once and a while but my doc says its healing....
I believe different pains come from gas build up. I have a couple band friends who complain about sharp pains like that but they do not last.
When in doubt , pain or fear its always a good idea to contact your surgeon
I have found the more i stay away from sugary drinks (like gatorade and juices ) the better i feel.
My Dr has me on liquids for 3 weeks which will be over Oct. 1st, which is my B-day! How is that for planning!
Hope to stay in contact with all sept. bandsters...
