Because if you have high inflammatory #'s in your blood work it could be an immune issue, thus you'd be a less desirable candidate. It gets complicated - if yours is simply and clearly [from all tests?] a diabetic type neuropathy you mite get in quickly. Otherwise, they mite not accept you. Don't feel 'rejected'? It comes with the neuropathy territory.
As for 'pruny fingertips'? I too have it? This web site helps some in explaining things [but I've an immune type neuropathy-doesn't mean one who doesn't have an immune PN can't have similar symptoms?]
http://telemedicine.org/stamford.htm Go to the 'diabetic neuropathy' part of the index? First read the 'Abstract, then the Index' then go to read about the diabetic PN's....most except for the immune related ones have similar side effects and one of them is the lack at times of sweating or oil productions on your skin and thus VERY DRY and or pruny skin. Find yourself some good quality moisturizers such as lubriderm or Eucerin or the like and slather away!
Don't forget too? When you get stressed? You'll likely get 'pruny'. Goes with the territory somehow, again? Slather away, but try and find lotions that are less greasy and more simply moisturizing and actually soak into your skin fast.
Beats getting so dry you have BIG dandruff and huge itching all over!
Hope this helps a bit? Let us know how it's working out for you. -'s - j
