While pain medication can reduce the discomfort you are having, it will not eliminate the cause. I suggest that you get a second opinion from a doctor with lots of experience in treating J pouch problems. Unfortunately, doctors like your PCP often recommend an ileostomy without considering the quality of life that their patient desires. The two alternatives to a conventional ileostomy are the K pouch and the similar BCIR, both of which do not require having an external bag and both have high success rates. I would definitely stay away from “street” drugs due to lack of quality control.
I have been working with the top center for digestive disease in Orlando and have worked with two of the best colon rectal surgeons in Orlando as well.
