Perhaps there was no withdrawal since you were taking enough oral morphine when the pump was removed. The pump can provide far superior morphine pain relief than orally. My experience has proven to me, that the pump was great at relieving my terrible chronic pain, for which it was set up for, but by no means did it make me pain free. I suffered pain from other sources during its use. Your posts indicate a similar situation ( pump removal because if site pain) . Oral morphine (enough of it anyway) affects all pain in the body, to some extent. I am not surprised that your chronic pain increased, because the pump is so much more beneficial, providing far greater accuracy and dosage that is impossible orally. Since you had a medically valid reason to have it removed, perhaps an option to have it installed in a different area might be appropriate. After all you had 20 years of success with one. They are making them much more compact (although the reservoirs are smaller needing more refills) which might help. Also, the procedure should be much simpler than initially since they probably left the catheters in. Although my situation is different, the pumps have their benefits, and in your case it might be the best option to live more pain free again.
