"i have arthritis and i am waiting for a hip replacement. the cartilage has gone in my hip. i am walking on bone on bone with terrible pain.  i take 4 - 8 tablets a day depending on the severity of the pain. ultracet controls the pain perfectly and i can walk almost normally. i have been on the medication for about 4 months now with no side effects. it&#039;s brilliant and i would recommend ultracet for pain relief. it is the only painkiller that works for me."
