I've been exactly where you're at. If things got so unbearable, what would I do and how would I do it? But so far, I'm not there. I use Ketamine cream (mixed with other pain meds) on my foot. That seems to help a lot. Additionally, I'm on Lyrica which really helped but also adds weight, Cymbalta, Tramadol & Tizanadine. I think my pm's thought is to hit it with all there is to keep it knocked down as much as possible. If another part of my body starts to hurt, I use a lidocaine patch there. I also use the epsom salt soaks and do the pt that my therapist taught me. I hope you find some relief soon.
