Yes, chronic pain breeds depression...fact of life.

I live with whole body chronic pain 24/7 from an accident that could have killed me. I lived the first several years without any meds, as no doctor cared.
One of my additional pains comes from the EMG I had where the doctor damaged the nerve he was testing, in my left thumb. No one has bothered to address that though, and in the scope of things, I guess it doesn't matter at this point.

The best we can hope for is good pain management, and maybe a future fix. Do you have a therapist to help you with pain management? I couldn't live without mine, personally. After 20 years, I still need (yes need) to see him 3x a week.

Tell us more, if you're up to it.
