Don't accept the pain
Pain can be controlled, easily, but only if you are willing to argue with your Dr.
Remember, all pain medication dosages are based on the fact that 50% of the people at the average weight said it helped. That has NOTHING to do with you, the way you feel pain, the amount of painkillers you need, etc.
According the dosage guides, they can double or quadruple the amount, as long as the patient keeps asking.
