Hello, I am a cancer patient and was on 200mg of morphine around december 2004, as well as percocets
. For pain relief. I have been off all narcotic pain medication since, and have been taking some Acetaminophen, aspirin and caffeine tablets for migraines I have also been getting. However, because of the high tolerance for pain meds I have now, I have to take about five of them to help for the migraines, and I notice that I get chest and extra abdominal pains when I do take them.
