Is this  LICHEN? Please help

Hallo. Sorry for my bad English. For 2 years ago I got a prolaps in my back. Then I got urine leakage due to paralysis from the prolapse. I think i started to itch from allergy to panty liners. Tried to switch brand. it helped some. But not quite. After many many creams I have maby found a barrier cream against urinary tract. I also use dermovat on wounds. But is this from allergies exema, viltago or lichen? I have been with my private physician, gynecologist and dermatologist. No answer. The dermatologist said it didnt look like typical LS. But I have a bad fealing it is. And wonder if I have to go to a more expensive private dermatologist. I dont have so many wounds now. just a very small one once a month if i have forgotten to use barrier cream.
