headache
"I had a spinal tap recently and unfortunately was in the small percentage of people that have spinal headaches from this procedure. I've had migraines forever but a spinal headache is by far the most debilitating experience. I was prescribed fioricet and was taking 2 every 4 hours it did nothing! I was back hospitalized the next day. So this may work great for migraines but anyone prescribed this for spinal headaches it does not work."
