 [ Symptoms ] whats the difference between norco and vicodin when they are both named hydrocodoneacetaminophen  i think it was an error on the part of either a nurse or the doctor but after being discharged my prescription list read hydrocodoneacetaminophen 5500 vicodin and the second one read hydrocodoneacetaminophen 5 325 norco so i am confused am i supposed to take them or is it a mistake because they both named the same somebody let me know if they made a mistake i do not feel like getting addicted or overdosing if its the same drug they game it for my back pain [ Disease ] hi it seems that the 7 years old knee injury that you had has not healed completely till date it may have been a ligament injury and such injuries if not treated adequately at that stage will give lifelong problems the knee seems to have accumulated fluid now effusion it will go away by leg elevation compression bandage analgesics fibrinolytic and anti inflammatory tablets local gels with hot fomentation will help even if it heals i suggest you should get an mri of knee done to prevent any further damage thanks
