Idiopathic PN,

Your SOB should be investigated further, by a pulmonologist. Lung damage from Sjogren's (typically, interstitial lung disease) can easily be seen on CT...so can Sarcoidosis. The SOB could also be cardiac in nature. Either way, it should be followed up.

Being diagnosed with Sjogren's with no dry mouth, no positive blood work and no biopsy is uncommon but I'm glad Dejibo is being treated just based upon symptoms regardless of what the underlining problem is...that's all that matters in the end.

Sometimes the cause of our PN and other problems is evasive. I hope you are at least getting suitable treatment for your PN, eyes, and find what is behind the SOB...so that can be treated as well.
