If anyone had any ideas I would appreciate it. I have had one single headache for 27 days now. I have been through 2 MRI/MRA's and have had a CT done, nothing has been found. Along with the headache is an unusual pupil. One is larger than the other. Pain meds and midraine meds do not seem to get rid of it ,just dull the pain. No one I see seems to have any answer for why I can not get rid of this headache. Does anyone have any ideas that I may try/
