Do you not have an IBD nurse you can contact? When I was having these problems I could call her up and she would slot me in that same day or give me advise in the interim to getting investigations done!
If I'm honest I wasn't sure if It had cleared myself. I had really irregular bowel patterns for months after and subsequent scans showed I was still loaded even when I was going regularly. Took months of laxative use but I found that soon I didn't need the laxatives to go, when I was loaded if I didn't use laxatives then I wouldn't go that much. I would take the laxatives and be going so I would think oh ok it must have cleared now but evidently it all hadn't so as soon as I stopped just started to build up again and I would get symptoms.
I also found that symptoms, such as the nausea and early satiety, started to ease as it finally cleared.
Sorry I can't be more helpful, it was a confusing experience for me too!
