Topic Explanation
The forum topic is about a person experiencing itching and irritation under their ostomy pouch, despite using a one-piece Hollister. They have tried using a smaller pouch but still experience itching and blister-like irritations. They are seeking advice and ideas to alleviate this issue.

Advice and Insights
- Consider using a puffer inhaler, suggested by a stoma nurse, to spray directly onto the rash to allow the bag to stick without any problem.
- It's possible that there is an allergy to something in the pouch, so trying different brands like Coloplast or Convatec could help.
- Contact the manufacturer of the pouch, such as Hollister, for assistance and advice.
- Experiment with making custom baseplates to stick the pouches to, tailored to personal measurements and specifications.
- Check if tiny hairs are being pulled out when removing the wafer, causing irritation with the new wafer.
- It could be an allergy or fungal issue, so consulting a doctor for antifungal with a steroid or skin prep could be beneficial.
- Consider consulting a dermatologist for medication or relief, especially if there are additional skin conditions like psoriasis.
- Monitor diet and consider reducing sugar intake, as it may contribute to increased itching.
