This is exactly the pattern I have, although I also have paresthesia in my lower legs (feels like fizzy water undulating up and down my legs) before the onset of the burning. I’ve recently been diagnosed with length dependent axonal sensory neuropathy after having a nerve conductivity test. I sometimes have a few nights when it isn’t as bad, but when it is, I’ve trying everything to stop the burning and get to sleep. I still take supplements like PEA, ALA, NAC, and use topical creams like magnesium and capsicum cream. I’ve recently been experimenting with compression socks. To fall asleep I’ve tried Kava Kava and cheery juice… I’ve also tried gabapentin and nortryptiline, but don’t tolerate them at all. None of these things have been that helpful and some nights are intolerable. The only thing I’ve found that at least helps me get to sleep - eventually - is ibuprofen and CBD.
