My PN symptoms started three days after a car wreck in which I helped sweep up the glass and refused to go to hospital. It is 2yrs gone by now and I am better. Seems some of folks have an acute phase. My journey included muscle wasting and motor function. If your improvement is dependent upon nerve regeneration, that takes time. I am not well versed in SFN but wanted to tell you that it ain't over until its over. Good Luck, Ken in Texas.

when did you feel like it stopped getting worse and started getting better?

Could not resist ripping off the three stooges. As it has been two years, I feel one year was a descent marked by pain that moves and changes. Left side involvement 60 days after trauma. At the worst I could not manage a sidewalk curb using a walker. Now I am practicing walking without the walker at all(inside the house). Lost 60lbs and now gained 20 back, still need to lose a lot because I know that would help my mobility. There are few hard facts with Neuropathy as I read posts,the old disclaimer applies"results may vary". Good Luck, Ken in Texas.
