Lichen planus! Should i take that?

So initially my lichen planus started as a dark pigmentation in my buccal mucosa, then i started applying kenacort and then later caziQ, as they were prescribed by dentists and dermatologists, when I was applying them pigmentation was fading but when I stopped it aggravated that. Then since 1-2 months I have stopped using any steroids as my dentist said. I dont have any burning or itching or anything, just buccal mucosa had becm rough, and mouth felt dry smtyms.. i was also taking homeopathy treatment, dryness and roughness was under control. But recently i saw increased itching throughout the body and also red bumps came up in arms, thighs, side belly. I have been prescribed steroid cream(HHFudic cream) twice daily for 10 days. But i am afraid if it will ultimately aggravate the condition just like it did in mouth, should I take that? Please help, m worried.. attached image of the bumps in arms.. I am non smoker/tobacco. I am getting red spots in multiple places. Plz advice and help
