Welcome to NeuroTalk:

I do believe that 30 days is not long enough to stop simvastatin side effects, depending on how long you have taken it. Some posters here have had permanent damage. Some have reversed using supplements carefully, that affect mitochondrial functions.

I also would like to ask if you are supporting your lost CoQ-10 by this drug by taking a quality form in a supplement? ALL people taking statins lose CoQ-10 in the body, because the drug blocks the enzyme that normally makes it for everyone.

We have and have had posters here who think their PN was caused by this drug.

It is also possible this drug acted in concert with some other factor, such as hereditary risk, or with other neurotoxic drugs and/or chemicals.

Do you know why this nerve was compressed? What caused that?
