Girija,

Not too long after I was diagnosed with PD iI developed a a rash on my hand. After months of dermatologists with no answers my pcp had me tested for everything. The only thing of interest that turned up was the HLA b27 marker.

It turned out the rash was a fungus which meant it has nothing to do with anything, but my question is, is this the same "family' (?)you arre talking about here?

I have never had any of the named conditions listed in Wikipedia (my source for everything) except i do have osteoarthritis and have had both knees replaced due to it.
