If you are from a state that has medical marijuana this might be for you:
My general practitioner recommended I try medical marijuana. The first time was a bit disappointing; I was extremely anxious / confused and my feet were still on fire. Back to my Dr. and he tells me I am using too much. He explained that Large doses of THC create anxiety, racing thoughts, and increase psychological stress. In smaller amounts, THC can promote relaxation, reduce anxiety, and ease the psychological tension linked to chronic pain. THC does not directly affect your feet, it works indirectly by reducing stress. The stress reduction calms the central nervous system and reduces the perception of chronic pain. Managing your stress improves overall sleep quality and the emotional burden created by chronic pain. Remember, marijuana does not treat or reverse the underlying cause of nerve damage; it is used for symptomatic relief.
I stopped smoking and switched to orals (better dose control), the improvement was immediate. It doesn't stop the pain but it slows down my anxiety and helps me to focus on things other than the pain.
I started with 20mg capsules and it worked great for a couple of years. I have built a tolerance and I currently use 50mg. I recommend you start slow with lower dose (10mg) and work up from there. Be aware that orals can takes +/-2 hours to take effect. If you are a new user be aware that it can cause dizziness, lightheadedness, and slowed reaction times.
