I’d guess you might have a stricture rather than constipation. Is there a particular reason you think it’s constipation? Go easy on yourself, and try not to strain. This would be a good time for a pouchoscopy if we weren’t experiencing a pandemic. Maybe try to schedule one with your GI for 8-12 weeks from now, and hopefully it will seem like a good idea as that time approaches. You could also call your GI for some advice.
