Hi Laurie! I'm Stephanie btw. Could not get my name in there somehow. i think the inner lip will be okay but not sure about tongue. I still think you will be okay as mouth tissue heals really quickly.
Hate to hear about all your immunocompromise, really frustrating. I sure hope you don't get shingles, got enough going on.
I am looking into boosting my immune system as this OLP seems to be a real puzzle even for the "experts". I think much of this is related to allergies and immunity.
Yes, it's an awful affliction. Take care of yourself best you can:)
