I have peripheral neuropathy as well but it was dx at around the same time so not sure if connected. I also developed severe eye problems and though dx with belpheritits and dry eye they feel it may be rsd but who knows. I also developed seborehic dermititis. Through this I have other health problems and went to doctors for auto immune conditions cause for ex I have a lot of symptoms of sjogrens but never was dx with it.
I think a frustrating issue is that each speciality just likes to look at there one area and may not connect symptoms and dx. Some major places like Hopkins I heard does but I don't know that for a fact.
Hang in there and i am sorry about your conditions
