No cure eh? Well, then let's hope that's not it. I had thought it was a parasite, which if it was it should have a cure, though maybe not western. Parasites could be handled with internal and external medicines. Boosting your immune system and taking parasite killing herbs would help internally. While externally you could use things like seabuckthorn oil, east cape manuka oil, and tea tree oil to kill them. Then keep your house clean and do a parasite kill. Clothes, furniture, bedding, mattress, etc.
Anyway, hope it's something easier to fix and diagnose. If it is a parasite, keep what I said in mind and learn more about other options too.
