"i am a 51 yr old male with cervical  degenerative disc disease. i&#039;ve been on 10 mg norco for approximately 3.5 years but recently my doctor changed me to 7.5 mg percocet because i&#039;ve become tolerant to the norco. my pain level hovers around 4 or 5 constantly but the percocet allows me to maintain. thanks for this medicine."
