"i am a roofer and have fallen off of ladders and roofs. i&#039;ve got pinched nerve in shoulder and muscle spasms in entire back daily. after trying lortab, percocet, norcos, and a few other pain medicines my doctor gave me nucynta 75mg. finally after 7 years of agonizing pain i can actually function almost normally. it works very well. no buzz feeling just no pain."
