LP is treatable but never cured. I use Clobetasol gel for for lichen planus sclerosis on vagina, clobetasol liquid for head. For my mouth I use Dexamethasone mixed with Nystaton. This a liquid steroid and with outbreak, rinse four times a day. Breakout at different times but using these drugs have kept LP under control and of course commitment to meds and lots of patience. I go to the only dentist in the largest city in US and past year have gone to Gynocoligist for vagina. Was going to dermatologist but was not very successful. Now I find out about escophageal LP which I did know about and am shocked. Scheduled for test on throat and hope it just needs to be stretched. Problem swollling.
Have had LP on and off 12. Hope I have been of help.
