A lot of narcotics can cause a side effect called Headache disorder. Both of the medications you are taking have that safe side effects. You are most likely experiencing headache disorder. It can go away with time and it can also last as long as you take the medication. (This is rare though) Talk to your doctor about it as he or she can prescribe something for the head aches if you have chronic pain and need to be on those medications. I hope this helps. Good luck to you!
