Dear Doctor, I have been on Flexirel and Naproxon for treatement of jaw joint pain TMJ as I wait to see an oral surgeon. However, I have an ichy rash on my chest near my throat . I stopped taking the Flexirel but the rash hasn t abated. I know it could be the flexirel but could it also be the naproxon? In any case, how do I treat the rash? Thanks so much, sm
