Black mold specifically hasn't been identified as a known trigger for prurigo nodularis. However, environmental irritants and allergens more broadly can play a role in triggering flare-ups.
What is known is that an overactive immune system is a key factor in PN. Certain infections and environmental exposures can push the immune system into overdrive, which may contribute to PN developing or worsening.
The types of infections and exposures currently linked to PN include:
- Bacterial infections (such as H. pylori and tuberculosis)
- Viral infections (such as hepatitis C and herpes zoster)
- Parasitic infections
- Certain cancer medications
- Underlying health conditions
If there's a concern that mold exposure may be affecting symptoms, it's worth raising with a dermatologist or doctor. They can help investigate whether an environmental factor might be contributing and recommend appropriate testing.
