I have been on Norco for 8 years and now on Percoset 10/325 2T Q 6hrs for the past 2years. I had no effects except relief of pain and now I am starting to feel very tired often and muscle pain. Has being on this medicine for so long damaged my body? Should I stop taking it? It is all with a legal face to face doctor but I am starting to wonder if I am starting to have additional problems and if the pain relief is worth it?
