I'm the opposite, ice is the only thing that calms my spasms. Too bad they start again as soon as my feet hit the ground.

I do, too, except I found that it works best if the heating pad is under my lower back. The heating pad on a timer works even better than nerve pain medication in relieving the nerve pain in my feet at night. My autoimmune-mediated peripheral neuropathy was caused by the Covid vaccines, and I believe the dorsal root ganglia neurons near my spine were also inflamed. That would explain why the lower back placement of the heating pad helps so much. (I don't have any orthopedic issues.)
