John, thank you for being a mentor and thank you for the great links to related discussions! You are right that I have two overlapping initial messages - the first one did not show up on the web page, so I prepared another similar message. Now both messages appear - sorry.
The complementary treatments I have tried, and results, are as follows. Lyrica 50 mg reduces night foot pain, but higher doses or a daytime does leave me too groggy and spacey. Could not tolerate Cymbalta (stomach issues and headache). Ice gel packs on feet help at night. Surprisingly, so does taking a hot bath. Plantar fasciitis boots help a little.
I'm a fan of using lidocaine patches on the bottoms of my feet at night. Tried Rugby capsaiscin cream but it made the bottom of my feet feel burning, and it didn't provide any relief.
A sports medicine doctor is doing nerve blocks on individual foot nerves. When she's found a nerve contributing to foot pain, she is doing prolotherapy (injection of a sugar solution near the nerve to create more space for the nerve and nourish the nerve) - that is helping someone. She suggested alpha lipoic acid, vitamin B1 (I already get ample B12 from a daily vitamin) and magnesium. Just started them 2 weeks ago, so too early to tell. Plus, the magnesium seems to irritate my stomach.
I occasionally use a TENS unit when daytime pins-and-needles sensations are bad. It seems to reduce those sensations.
I tried acupunture, but it didn't help me.
Hope this summary helps others.
