hi i had a colonoscopy just over a month ago , which was thankfully all okay, apart fro. 3 internal piles . so i went back two weeks ago to have them banded (much more painful than i anticipated. however two weeks on, i still get terrible wind and bloating every day. has anyone else experienced this. before the procedure, i was not at all gassy, never have been, and now its starting to worry me a get me down.. can anyone relate? thank you j
