Hi there, my wife has had PN in her feet/ankles for 6 years. She does not do well with drugs and hates the thought of taking them in any case. Like you, she got no help from gabapentin and quit it. You ask for ideas. Here is the regime she follows:

1. healthy low sugar diet
2. 28 different supplements, best quality ones she can find; the ones specifically for PN include include benfotiamine, r lipoic acid coupled with acetyl l carnitine, Theracurmin (curcumin product recommended by @jeba ) for inflammation, and PEA (PALMITOYLETHANOLAMIDE).
3. she uses Penetrex (roll on, not the cream) on her feet before going to bed as it calms the pain down by about 30% for long enough to get to sleep. Before applying the Penetrex she soaks her feet in water, as hot as she can tolerate, which seems to help.
4. She has an electric fan blowing on her feet both during the day when she is sitting and at night while sleeping (she sticks her feet out at the end of the bed).
5. she keeps her stress level WAY down at all times and does not leave home most days. She tries to get regular sleep and enough sleep
6. She uses cannabis and kratom when her pain level goes beyond her ability to tolerate it.

Using these methods, she is, so far, managing to cope with her pain. The one thing that is lacking in her lifestyle is enough exercise. She says she is too weak most of the time, as she gets really hammered with the severity of the pain. Hope you find some or any of this helpful. Best, Hank
