"i tore my adductor muscles from slipping on some mats in a martial arts class 6 years ago. i&#039;ve had two sports hernia operations which helped but i have some permanent nerve damage in my thighs. i get burning and shocks in my thighs. i have been taking 1-2 norco as needed for several years and they work great. i know they are highly addictive but no other pain killer allows me to work, have fun with family and friends, and continue to train in my martial arts. i sometimes go 3-5 days without any and rarely take more than 2 a day. if you have chronic pain or permanent nerve damage these can give you your life back."
