Ok I am in the same boat 5 years down the road. I am going on 13 days with this headache Nd am currently hospitalized to find a cure. My pain is severe with nausea. Krishna is clean, spinal puncture is clean. No meds seem to remotely effect the headaches not even newbane a strong narcotic yes it made me stupid, but it just made me stupid with a headache. Point of the matter is I am getting a little worried.
