What I thought might be me getting a tiny bit better might just be progression???

Lately , (last week or two) my sensations seem to be getting a bit more dull. In it's place I seem more " heavy and numb" ( not actually, but feels this way) and much more burning in lower arms and legs that feels like somebody peeled my skin off and it's raw. the electircal sensations, buzzing , twitching etc seem to be slightly more dull or happening with a weaker intensity.

Does this simply mean that my nerves are simply gone ( small fibers) in those areas or that they are now so damaged not as many can send out these signals? Am I headed down a path of no return here in terms of healing?

Why is mine continueing to progrss and change so quickly? Why isn't it stabilizing ( like so many on here claim) or improving. Why the continued rapid progression?
