I have been taking 2000 mg seroquel daily for about 5 years. A few months ago I started experiencing pain in my right leg. It has gotten worse and my doctor took me off the seroquel, but the pain is almost unbearable. I am now on painkillers and I need a cane to help me walk. Could this be the result of years of heavy seroquel use? Please help. I am at the end of my rope.
