it IS. That means daily checks and moisturizing as the lymphatic system mite have been failing in this quarter. IT happens. A really good podiatrist helps here to trim dead callous and nails when you aren't walking on them 'normally'.
This site is useful: http://telemedicine.org/stamford.htm Click on it, then go to the Abstract and then the Introduction....these are key to understanding what all happens to the blood vessels, nerves and vascular/lymph systems that all come into play in the LIVING with PN.
I must ask, IS it getting WORSE? or just status quo? Getting worse would entail getting second opinions, and that it mite be something more complicated...which I hope truly, it is not.
In the meantime? Treat your feet as IF you ARE a diabetic. For starters, a good lotion is Eucerin Calming Cream and try that...got some mild numbers in it and lots of good moisturizers. A dermatologist can prescribe if needed, stronger moisturizers and conditioners - a thing I do. Don't mess around with neuropathy feet! You get a blister? You mite not know, and, IF not cared for right, you could end up for quite a while in the hospital! {And on hospital food to boot! YECH!} Treat your feet as treasures! After all, the ways to get around without walking on them, are really, really inconvenient and often nasty, and complicated! I've been there!
Hope and keep at it! - j
