GET YOUR MEDICAL CARD
You may want to try the products at HerbaBuena.com or in a local dispensary within your state. There is a topical balm with 700mg of THC / 28 mg CBD per bottle (my clinical experience & the medical literature show that THC may be more useful for neuropathic pain).
One can always make your own topical preparation. Here's a recipe for a coconut-infused oil (that you can use in cooking as well as in making a topical salve) and another recipe for making a salve, both from the HelloMD archives. I hope that all of these prove useful!
