Yes, what your describing would be somewhat common symptoms of SFN.

It's also very common for the nature, severity, and location of symptoms to vary over time - Sometimes getting progressively worse, other times waxing and waning, and occasionally getting better over time.

Mine have been waxing and waning over the past several months. Just when I think I'm getting better they get worse. And when I start thinking things are hopeless they get better.

Hopefully, things will turn around and get better for you soon
