Ketamine is an option I’ve thought about trying we have a clinic where I live my pain never stops and I have tried everything as well and I have a implant tens unit that I never turn off I sleep with it on 50 and Gabapentin at 4500 mg’s a day with cymbatla my pain laughs at all the meds I’m on . No end to the pain and as you said
they look at you like your crazy
