Hi, I was diognosed with pemphigus foliaceus almost 5 years ago. Tryed many medicines including pednisone. Still gets bad flare ups, and each time in a different place, which means it will always be there, i have it on at least 50% of my body including my scalp is coverd. Is there any break through with other medicine that are not so invasive? And is there a pemphigus specialist, because most dermatoligist dont know much about the disease.
