I've had a few different places, and diferent things help, depending. I find magnesium and potassium supplements keep it to a minimum to start with.

Stress is also bad - not enough sleep, too cold, not eating right. All that makes me feel not so good also makes the nerve pain worse. I may not notice for days or a week, but it'll come. Took me a long time to make the connection.

Ice or heat will mix up the signal sometimes, either stop it or make it less painful (but I have to do the ice or heat as soon as it starts or it doesn't seem very effective).

Stretching makes it worse for me. I never excersize when nerves are acting up due to that. Walking is okay, but yoga is out of the question.

Amitriptyline worked well for me.
