can you have raynauds syndrome in just one finger?
I am extra curious to know how you have progressed since typing this question. Mine started in my right thumb, then worked its way to the littlest finger, and then started its way down the other thumb (six of ten affected so far). SO...YES...it can begin in just one finger. in my case, the peripheral circulation restriction causes my outer layers of skin to die off on these fingers. It's a special inner ring of Hell, as I'm sure many already know.
