Been there done that, see adoctor of neurology asap. First most narcotic pain meds will cause headaches because they shrink the blood vessels in the brain(sort of the same feeling as a hangover?) My cure was as told by a very wise person from Johns Hopkins who told me to take 2 asprin a cup of coffee and lots and lots of "PURE" water. The need for a doctor asap is the tiredness in your face could be youve had what they call a "MINI STROKE" and time IS OF THE ESSENCE if you wanty to loessen the chance for a full blown strokeYou didnt say if you are female, but if so RUN DONT WALK TO A NEUROLOGIST.. GOOD LUCK and God bless you in your journey... HURRY!
I did have massive headachs for weeks and weeks last year. I tryed every kind of headach pain realver medicane out there but it turns out it was just a UTI so you might want to get checked out for that. You never know. It never hurt me to pee though or anything, i had no signs of one but after they tested me for it and i finshed off the medicane my headachs were all gone.
An endless headache may mean that you have a serious problem,you must go and see a specialist to see what causes the headaches because you may not know it might be a brain tumure.Taking pills forever may cause another problem
