My comment on drugs is that there aren't any that work for PN, not to mention that all drugs are toxic. The side effects of drugs even when they seem to work are collectively worse for you than what they were prescribed to treat. I try to avoid them if at all possible; with two forms of cancer that haven't been totally possible. With all due respect; you said enough about your TENS experience to inform us that you never learned the correct way to apply it. I also have never seen any TENS device that had suction cups for electrodes.
