"i have scoliosis that causes sereve pain, my spine is s shaped. its a pretty severe curve. anyway been to a number of doctors, finally got a pm doc that prescibed a number of pain meds that did not work, i almost gave up until he prescribed oxycontin. what a relief, now we have to adjust the dosage a bit but finally got it perfect, i take 4 40mg pills a day and been on that same dose for about a year and it is still working great, i am not building a tolerance to it at all."
