Hi, I have been taking Norco 10/325 for about 2 years due to a fractured collar bone, shattered shoulder socket etc and 2 surgeries that didnt go as well as planned. On a bad day I was usually taking between 5-6 pills and when the tolerance starting building I went from 7-8 per the Docs instructions. The Norco 10/325 had been working fine but last month it stopped working. Very little pain relief and even that euphoric feeling went away. So my Doc put me on Percocet 10/325 stating that he would keep me on it for about a month or 2, to give my body time to get rid of the tolerance to the Norco. I thought this was odd since the Percs are said to be much stronger. Will taking the Percs actually help the Norco start working again? The Doctor said that my body will think that I havent been taking Norcos and it will start working like it did when I first started taking them.I just figured that if I took something stronger than the Norcos my tolerance would build even higher. Can someone give me some medical insight here? Just doesnt seem to make sense?
