You may be experiencing a partial blockage, you would feel bad and would cause "constipation" and the other symptoms. You may still be partially blocked. I definitely think you should consult with your GI.
When I have had partial blockages I usually get on a liquid diet to help things out. Make sure to keep moving to help things along. I also end up taking antibiotics because pouchitis usually follows. Pouchitis also seems possible, I feel similar but not actually constipated.
Good luck
