Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. The location and movement of a pain gives clues as to what is going on, so, it if shoots outward, has electrical or temperature or circulatory components, it probably is a nerve. Nerve pain responds to nerve pills and there are a lot they are quite good for it and quite safe and affordable. Amitryptiline with its lidocaine effects is actually better than a lidocaine patch because the pill goes deeper. Also, nortryptiline or cymbalta work as pills. There is also surgical intervention to block the nerve. Hope I have answered your query. Let me know if I can assist you further.
