I've suffered with sciatica off and on for years now i'm trying to figure out if the burning in my feet and lower legs is from sciatica . It seems to be almost gone from now my new water exercises . I had been diagnosed with small fiber neuropathy this summer from a normal emg test and with all the other tests it would have to be idoipathic as no source . Anyone have similar burning ? I have a few discs that are not too good in lower back but not bulging or herniated.
