Lichen planus and Sclerosis

I have chronic Stills Disease which is an AI condition that for me manifests as RA.

I have a diagnosis of Lichen Sclerosis and Interstitial Cystitis which started during menopause.

In recent years my constant sore throat which accompanies Stills Disease has got worse and a new torso skin rash has inundated my skin. I’m wondering if this is LP.

Anybody have experience of both or combined with rheumatoid conditions?
