Just thinking of starting a thread discribing my neuropathy, but you did it better then I can do. (I have the same sensory sensations, including the piriod ect.)
I feel the same, seems that I have the same symptoms. Lately I was diagnosed as light SFSN - might be toxic NP. But can be also sort of sensory GBS.
I think that instead of looking for a name - we have to look for health. Find what helps us (like rest, without stress, eating well and so) instead of digging and trying to look for a name - because there is no name except of neuropathy and this - we know. in those cases when the reason is not clear - the doctors consider it as idiopatic.
Remember - you were in stress 3 years ago, which means that your imune system wasn't in its best condition, becides taking some medicines - this can couse neuropathy from the toxic type or viral type. in this case - it was one onset and that's it. the damage was done - and that's why you have all this kind of sansations, but it won't progress, or may be very slow. So remember to think positive...
