I am not sure if this will be helpful to you or not, but I was recently
diagnosed with Pyostomatitis Vegetans, ulcers on my lips. These
painful ulcers went undiagnosed for a couple of years until I was
finally diagnosed with this UC related (rather rare) disease at
They prescribed Clobetasol Propionate 0.05% and Protopic 0.1%
ointments. My ulcers cleared up within 48 hours and with periodic
use, these meds keep them at bay.
