Everybody's experience is a little different with this syndrome so there isn't going to be a magic bullet. In my case the intensity of the pain tapered off as the nerves apparently died off, or it stopped progressing. You might check online for sites that are specific to PN like https://www.foundationforpn.org/ Also, some major clinics and universities like the University of Chicago and the Cleveland Clinic have sites that discuss it. There is unlikely to be an quick fix although everybody wants the same thing, a cheap over-the-counter solution. As far as over-the-counter stuff, alpha lipoid acid might help some, but everything has side effects. In my case, I just keep walking, mostly to steady my gait. Hope this helps.
