My Doc is also looking at my one of my meds I take. He is very suspicious because my symptoms are disproportionately more severe than the lung damage would warrant. The med is Zonegran. It is the one that helps with the skin pain of fibro. And I started it when the symptoms became severe. I just remembered this very recently. My Doc told hubs during golf last night he would dig further and get with my rheumatologist to discuss it.
