When I first got my PN? NOTHING could touch my skin! Was either too HOT or too COLD! I felt like Little Red Riding Hood, never finding 'just right'!
BUT? It got worse, to the point where for a long while I could NOT FEEL A THING in my legs and feet! Didn't know where I was putting them? Had to look, that threw me off balance and almost got back to normal...feeling and balance? Then all over again. BUT? I've a severe PN. One that keeps trying to 'progress'.
Questions for YOU now? IS it definitely positively diagnosed? If so how? Is it progressing? [Meaning, is it still crawling up your arms and legs closer to your torso?] How many neuros have you seen?
I hate to ask you these personal questions? But, most of us here have had to bleat out our 'conditions' and so forth to get the better guidance of those of us 'who have BEEN there'!
As for the skin? Eucerin 'Calming Cream' helps, as do other lotions and potions that have been posted in various parts of these boards.
http://www.eucerinus.com/products/hb_calming.html There are other products available as well. They're good for 'sensitive skin', and I HAVE IT! I have both small and large fiber nerve involvement. Sometimes both at once. It helps keep the skin moist as my body isn't doing it's job well in this quarter at all.
Read the Stickies about such things. OR pm me about it.
Yes, you can feel as if you are 'ON FIRE' at one time, then...shortly later turn into an iceberg! It's happened to me a lot? But after many years, it's 'happening' less frequently [WHEW?]. I hope this helps and don't ever be afraid to ask questions! Not one question is too simple or silly-seeming.
