I just found this pdf, (attached below) and in my own experience with lichen planus have seen some carbohydrate metabolism issues, though mainly I get more hypoglycemic (self diagnosed, it might be hyperglycemia) than I have in previous years. Also, just the level of fatigue is increased (but also, i am 74 and expect to be able to easily run marathons)..Keeping all in perspective, i am just trying to get to the best way to live with this diagnosis.

Five years down the road (it is now May 2023): This has never gone away, so i guess i am on the long end of this disease (commented at 7 yr in the literature) than the short end (1 year) and for me “stress” is certainly a factor, and there is a possibility that working with concrete and mortar might make things worse? No reasons for that thought except coincidence? since I have spent the winter and early spring patching basement holes, and tiling a bathroom. Who could make a connection? no clue.

Injury to superficial skin (like scraping injuries that remove epidermis) are definitly a contributing factor.
