I recently found out I have hep c. I'm experiencing more pain in my mid back,arms and legs can it be from the hep c? I'm on 400mg of morphine sulfate a day. I'm afraid to tell my back Dr I don't want to suffer and live in pain I've done it for mmany yrs before I got pain relief I could barely walk no quality of life what so ever till I was put on the morphine now I somewhat can enjoy everyday life. Someone please help me,Is morphine sulfate safe for my liver. I been on thus dose for about a year. Thank You
