Do you mean you feel like you have to go to the loo in the 'old' way? If so, this is a sensation called "Phantom Rectal Pain". Just like an amputee can 'feel' their amputated limb itch, so your body has to get used to it's new plumbing. It's annoying but completely harmless.
With a loop ileostomy, you may occasionally see stool coming out of your rectum and anus. This is because sometimes, the stool enters your second stoma (called a mucous fistula) and works it's way out as 'normal'. This is to be expected and very normal as well but can be scary if you're not warned about it.
Ileostomates can't really get constipated as our stool is so loose. We can, however, get blockages which means there will be no output - but you will know if it's a blockage. There's usually severe cramping, nausea and often you will have a temperature. If blockages last more than a few hours, it's time to seek medical advice. Ileostomies will usually work about 95% of the time.
Good luck and I hope by now, your ileostomy is back to it's usual self.
I have had an ileostomy for 31 years now due to UC.
