chronic pain
"Taking MS Contin 30mg four times a day for over five years. I use 4mg Hydromorphone for immediate release, breakthrough pain when and if needed. Usually (if needed) the Hydromorphone dose required is about 8 mg.  Because I am taking these medicines for a serious back injury in which I suffered 3 crushed vertebra, occasionally the pain gets out of control. Usually after ill-advised physical activity at a level beyond that which I am accustomed to. At those times it often requires the MS Contin and a dose of Dilaudid (Hydromorphone) to bring the pain back to a controlled level. When taking MS Contin and Hydromorphone together, there is a period of drowsiness that passes in about 1/2 hour. I just make sure I am not driving or out and about if such a dose is needed."
