I just printed out that blood test for treatable cause of small-fiber neuropathy; atthe very bottom it says statin use was found not associated with SFN! However, the one study pertaining to SFN and statins only included 5 mg of rosuvastatin. I was on 20 mg for 2 years (much too high most likely given my ratio of HDL to LDL and total). I don't know what to think. So much conflicting advice and studies. I didn't save that study.
