Is it consistent with small fibers damage?

No... Dermatographic Urticaria is due to histamine release *this wouldn't come from an MRI*
This is a picture of someone with Dermatographic Urticaria

Your back vertebrae WOULD NOT produce Dermatographic marks, it has to be an outside source such as you running your fingernail along your skin, it will make raised red lines, I get Dermatographic Marks and lines all the time.
I found you on Medhelp asking tons of questions just like these, I answered a few of them.... Here is a picture of your back you posted on Medhelp, these ARE NOT Dermatographic Marks, dermatographic marks are raised, like bug bits in a way, these are IMPRESSIONS

You yourself said you have these when you wake up :
"When I wake up I have a lot of marks/rinkles on my back and arms, etc, and a burning sensation without itchy..."
We can not help you if you wont let us, you continue to ask the same questions OVER AND OVER with no regard to what we've previously posted.
