Very best thing I ever did is find Dr Campbelland got all neuropathy gone so that was 60% of 30 yrs of pain totally gone, the wheelchair is home in storage now and after I did a series of Ketamine IV infusion was very successful. I'm getting in shape again on my MMA bag and I'm standing and cooking dinner all week. Before it was agonizingand depressing. Now I am much better, I recommend this treatment coz everything else I tried, it never worked, only this worked. Dr Campbell is a great anesthesiologist! Aloha!
