I was given an overdose of morphine during my pain pump trial. Apparently the test pump was set for the wrong drug concentration being used, it was set to give 100 times the required dose. When they started it I passed out and my breathing stopped, luckily my heart never quit but my oxygen level did drop below 70. They stopped the trial and administered a recovery drug to bring me back. So now I'm left with a chronic headache but no one seems to know for sure whats causing it. Has anybody else suffered a morphine overdose like this and do you have a chronic headache from it?
