|I also got first a very low dosage of prednesone, starting at 20 mg, then tapering down to 5 mg over 7 days. It did not do anything for me. After consutlting a different dermatatologist, she prescribed me a 4 day dosage of 60 mg, then 4 days 50 mg, etc. down to 10 mg. A much higher dosage, which still took 12 days to kick in. It was very painfuul, but it looks like its over now. My advice: Consult a different (means "better") dermatologist.
Be well, Marcus
