Does anyone else suffer from this? And how long does it usually take to recover? I have just recently had one of the worst flare ups of my life and it's been 10 days and counting counting and I'm still not feeling right. Intense fatigue, abdominal pains and diarrhoea are the main symptoms. I'm having a colonoscopy on Tuesday to see if there is anything else going on and I'm terrified that they are just going to write me off if they don't find anything. I currently cannot function as a normal human being.
