Hi, * Simvastatin is not a drug for peripheral neuropathy. It lowers cholesterol levels and is given to lower your fat deposition on the body, which can be due to diabetes and this in turn causes peripheral neuropathy. * Diabetes, which does not control /long standing diabetes can cause peripheral neuropathy. *Nerve compression at different levels. Vertebrae, discs, hip/local edema in the feet can cause such symptoms. Exact cause needs to be found by physical examination and needful investigations to be followed by specific medicines are needed. Physiotherapy/physical therapy /dietary management have equal importance as drugs. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Vasudha Jayant Athavale, General & Family Physician
