The b-a-c dosage is 50-325-40 every 12 hours. The endocet is 1 every 4 hours as needed for pain. The gabapentin is 4x per day @600mg each tablet totaling 2400mg per day. My headaches started as a result of a test my dr ordered called a neck discogram. I had a car accident 2yrs ago. I had a 2 level neck reconstruction. Drs told me that would cure my headaches no such luck. I need help I have all these drs doing finger pointing at 1 another. Please help.
