Hi, I Have Interstitial Cystitis And I Am On Pyridium

Hi,
I have interstitial cystitis and I am on pyridium at the moment, following a rescue bladder instillation on Friday. This evening, at about 8 pm I took a suboxonone, prescribed for pain. However, they were very old. I haven't taken them in about 5-6 years. I am having extreme difficulty urinating now, and want to know if I will need to be cathed and should go to the emergency room. I am able to urinate about a quarter cup. I am not in pain.

Thank you
