My long lasting pain medicine, Duragesic 100, which I've been taking for several years isn't working properly & I'm considering discussing Oxycodone with my PM doctor. However several years ago, when I was first injured, I tried taking Percodan or Percocet, can't remember which, but as a result had severe migraines. It's my understanding that Oxycodone, Percodan, & Percocet are basically the same medications, but with different additives. Still have migraines but under control most of year. Has anyone had problems with migraines because of taking this Oxycodone? I sure would appreciate any input on this. Thanks
