HEADACHE 4 DAYS NOW

MY NAME IS TIM AND I AM 47 YEARS OLD. HAVE A BACK PROBLEM THAT HAD GOTTEN TO THE POINT THAT MID APRIL DETERMINED THAT I HAD TO HAVE SURGERY STARTED TAKING 5MG HYDROCODONE 5MG EVERY 4-6 HRS AS NEEDED. AFTER ANOTHER MRI AND ALL LAB TESTS HAD SURGERY ON MAY 21. AFTER DISCHARGE FROM HOSPITAL DR GAVE ME PERCOCET10 AND PHENERGREN FOR NAUSEA. BEEN VERY STRICT WITH MEDS NOT EVER TAKING MORE OR SOONER THAN NEEDED. TOLD ME I COULD TAKE 1-2 AS PAIN EASED OR INCREASED EVERY 4-6 HRS. MEDICINE WORKED BUT NAUSEOUS AND MIND REALLY CONFUSED AT TIMES. FOLLOWED UP WITH DR ON MAY31 AND ASKED TO GO BACK TO WEAKER HYDROCODONE. STILL VERY STRICT ON THIS. EVERY DOSE WRITTEN DOWN AND NO OF PILLS TAKEN ALSO. AVERAGED about 4.5 5MG HYDROCODONE PER DAY. SUPPOSEDLY IT TAKES 3 OF THE HYDRO TO EQUAL 1 OF THE PERCOCET AS FAR AS PAIN CONTROL. THE PROBLEM IS NOW THAT I HAD AN EPISODE ON FRI NITE IN A LOT OF PAIN AND DECIDED TO GO TO SLEEP WHEN I AWOKE AT 5 IN AM BACK KILLING ME AND DULL HEADACHE WHICH TURNED INTO A SEVERE MIGRAINE TYPE HEADACHE THAT BASICALLY LEFT ME INCAPACITATED ON AND OFF FOR TWO DAY. STILL HAVE DULL HEADACHE WHICH WORSENS WHEN LAYING DOWN, NOISY AREAS, WATCHING TV. HEAD EASES A BIT WHEN MOVING AROUND AND IN DARK WITH COLD COMPRESS. ALSO NEVER HAD HIGH BLOOD PRESSURE BUT AT ITS WORST PAIN WISE OF COURSE BP WENT SKY HIGH. HELP....
