This topic is about a person who has been experiencing persistent rectal pressure and pain after undergoing a loop ileostomy and colectomy. Despite normal test results, the discomfort remains, causing anxiety and pain. Here are some insights and advice shared by others who have faced similar issues:

1. Normal mucus build-up:
- After a colectomy, the rectum continues to secrete mucus. It's helpful to sit on the toilet occasionally to let it drain naturally, without straining. The frequency of this varies for each person.
- You might notice foul-smelling, colored mucus or small lumps for up to 18 months, but this usually decreases over time.

2. Commonness of the pressure sensation:
- Many people report a similar sensation of pressure, often described as feeling like a "baseball-through-the-anus." This sensation typically diminishes over time, ranging from weeks to 18 months, but can occasionally return in a milder form.
- Distracting your mind from the pain can help, as focusing on it often makes it feel worse.

3. Time and patience:
- Some have found that severe pain resolved after about 11 months, though occasional pressure may still occur but is manageable.
- Others have experienced intermittent pain for 1 to 2 years before it settled.

4. Medications and topical treatments:
- Colifoam, a steroid foam, can be used to reduce rectal or pouch inflammation when accessible.
- Buscopan (Hyoscine Butylbromide) is an oral antispasmodic that can lessen pelvic and anal cramping and pressure, with notable relief reported within a week.
- Over-the-counter feminine pads can protect the skin from continuous mucus leakage.

5. Managing back-flow of ileostomy output:
- Loop ileostomies have two openings, and liquid output can sometimes flow back into the distal limb and exit the anus, causing irritation and pressure.
- Using absorbent gel sachets in the pouch can thicken the output to a "pudding" consistency, reducing reverse flow. These are compatible with certain ostomy systems.

6. General coping tips:
- Regular gentle anal irrigation or flushing can help keep mucus clear and odor-free.
- It's important to recognize that the problem is physical and common, and nothing is "about to fall out."
- Non-opioid strategies, such as antispasmodics, topical steroids, and absorbent gels, can help manage symptoms without relying on pain medications.
