"i have had chronic pain since 2002. i have reflex sympathetic dystrophy (rsd)  in low back both legs below knee both feet. long story short i have been on pretty much every pain med there is. had over 200 nerve blocks. had nerve endings burned off. pt you name it. now i have a medicine dosing machine inside my abdomen with a cath that runs directly into my spinal cord. i tried this hyslinga it&#039;s worked great. i&#039;m surprised so many people have not had relief from it. but if i didn&#039;t have the pump implant i&#039;m pretty sure i would be on the highest dose they make."
