I was on rosuvastatin (20 mg) for over 2 years when I developed SFN, but I have no idea if that is the cause. I read the one study from NIH about it causing neuropathy if used long-term. I also read that up to 50% of the people taking rosuvastatin had some neuropathy in the study, but it is still being listed as safer than other statins. Unfortunately, long term was considered over one year in that study. I stopped it, but my numbers bounced back up and there is not much room for improving my lifestyle since I have eaten a plant-based diet with lots of fruits, veggies, grains, etc. and always exercise. I chose to try Zetia. Recently, it showed that it has been working and my LDL has dropped to near optimal. I also take the omega 3 (from algae).
