I have had severe headaches and migraines the last 2 weeks. I go to the dr on Thursday for ultrasounds but this has to be something... Im second trimester with twins and I drink one pop a day but even the caffeine isn't helping anymore and Tylenol has never worked. My dr has me on Percocet 6 times a day because of health issues I was a chronic morphine user with a pain specialist but to wean off that he did the Percocet. I take it how I'm supposed to do I know it's not withdrawals I get weak with some of the migraines and my leg swells off and on when it's a bad day . The migraines will start at like 3 am and last me all day
