I agree with your concerns about being non-functionable when using pain mediation. Some side effect are more tolerable than others therefore, you might want to address this concern with your physician. A multitude of medications are available and often times one will be more tolerable than the other. Have you tried a fentanyl patch or low dose morphine? Please, keep trying in order to come up with a satisfactory solution. No one should have to live with pain.
