How can i get relief for nerve pain in my feet?

Depends on cause: Ideally the cause of the pain needs to be addressed, ie: nerve entrapment, neuropathy. Spinal stenosis. There are a few topical and oral medications that may help with symptoms. See a podiatrist.

See doctor: There are medications from vitamins to prescritpion meds depending on severity of condition.

Find cause: I suggest you consult with a podiatrist. You need to know the cause before you treat this.
