I was in a severe aircraft accident crash have many physical problems including shattered discs 6 fractured lumbars broken shoulder and ankle and the list goes on. I have been taking 10mg Norco and 10mg Zydone finding Zydone relieves the pain much more than Norco. Since I have been building a tolerance they don't work as well as before. Doctor starting prescribing Percocet 10/325 and does work much better generic Endocet this time the pharmacy gave me generic made by Mallinckrodt would like to know if anybody has had the different brands and could tell in your opinion if you think one brand works better than the other would appreciate your comments if you have tried the different brands both Oxycodone and Acetaminophen 10/325. Do you think one works better than the other? Would appreciate some feedback. Thank You.
