This topic is about someone experiencing a burning sensation after using a Marathon Skin Protectant stick on the skin around their stoma. They are trying to figure out what might be going wrong and are looking for advice. Here are some helpful insights and suggestions:

1. The burning sensation could be due to an allergic reaction or skin sensitivity:
- Before using any product around your stoma, test it on a small, unaffected area of skin to check for any reactions.
- Consider switching to a different brand and ask your doctor or stoma nurse for alternative samples.

2. Leaks can cause chemical burns, so addressing any leakage issues might help eliminate the burning sensation.

3. People with sensitive skin may react differently to various products. What causes irritation for one person might be perfectly fine for another.

4. Avoid using products that contain alcohol on the skin around your stoma, as alcohol can increase stinging and irritation.

5. An alternative product to consider is the 3M Cavilon Advanced Skin Protectant. It serves the same purpose as Marathon but is often reported to be gentler and more effective.

6. If your skin is already raw, try using stoma powder along with a no-sting barrier wipe (make sure it's alcohol-free) before applying the wafer. This "crusting" method can help protect and heal the skin.
