You might want to ask your question in the Neuropathic pain forum. Be careful with hemp oil from industrial hemp. Much of the available help oil is from China and grown with more chemicals than are allowed here. If you are asking about CBD oil, there is domestic CBD oil that is refined from marijuana rather than industrial hemp. Industrial hemp is still strictly limited in the US.

Hemp oil is also not legal in all areas.

Please be aware that there are many claims made based on limited anecdotal evidence. The research is just getting started.
