The topic at hand is about experiencing blood in the stool after having an ostomy reversal surgery. This can be a concerning situation, especially when accompanied by other symptoms like pain and bloating. Here are some insights and advice from others who have gone through similar experiences:

1. Seeing bright-red blood with little or no stool during the first week after an ostomy reversal, including J-pouch creation, is quite common. Many people have reported similar symptoms, and the bleeding and urgency tend to gradually decrease over time.

2. It's important to keep an eye on the amount of blood. If the bleeding continues beyond the early days after surgery or suddenly gets worse, it's a good idea to contact your surgeon.

3. Experiencing pain, urgency, frequent trips to the bathroom, and a sore backside is typical in the first week following an ileostomy or colostomy reversal. These symptoms should start to improve as time goes on.

4. Once your doctor gives the go-ahead, try eating small, low-fiber meals. This can help "wake up" the part of the bowel that was inactive, which may reduce urgency over time.

5. Keep your medical team updated about any bleeding, pain, eating difficulties, and bloating. This way, they can adjust your care or medications if necessary.

6. Everyone's recovery is different, but many people have emphasized that things do get better within the first few weeks.
