I Also get a burning feeling Doctors told me this might be due to nerve damage where the Bowel & bladders are rubbing due to the IBS It feels like cystitis but the burning is there all the time but there is no burning when i weeI have this issue as well. When my IBS is especially bad, the urination part also gets worse. I also have a burning feeling when I need to go really badly, but I was tested for infection multiple times and each was negative. Along with the abdominal pain and bloating, it's really terrible and especially bad at school (I'm in high school) because I have to ask permission to use the bathroom. Glad to know I'm not the only one though.
