This sounds like--
 

--there could be a vascular component to it; are there any positional differences in the onset or severity of symptoms?

Neuropathy of the small autonomic fibers can cause trophic changes along these lines; people with small fiber neuropathy often have autonomic symptoms that can include disturbances in blood flow, blood pressure, sweat response, and the like.

Also, a number of the vascular/connective tissue autoimmune conditions associated with anti-nuclear antibodies can produce such discolorations, and they also often produce neuropathy:

I would think you'd need a more thorough work-up at a major center or teaching hospital

I agree, I just can't figure out how to find the right doctor here, and what type? .... heck, I live 5 blocks from UAB in Birmingham Al.

I'm up for a vacation since I decided not to go to Puerta Vallarta so if someone could suggest some really good hospitals (in some fun cities maybe) to look at that would be great!

who to contact?
 

if I find a teaching hospital, what type of contact do i look for at the hospital if my problem concerns PN, Skin Dissorder, Pain?

Do i need to go through this entire, each doctor at a time? or should i start with like the skin, and move on ...

at 50..... this is where I want my momma to do all the work! :winky:
