Hi Jon, I just found the hemicrania busting thread and posted there. Yes I have been diagnosed with chronic paroxysmal hemicrania, however several neuros have said they felt like it leaned toward cluster headache however none of the traditional cluster treatments have worked for me but had not tried oxygen or obviously mm. Indomethacin does work, though I have had to up my dosage as the years have passed and it has horrible side effects for me, depression, fatigue , confusion, all come when I take a pill and lift after 3 or 4 hours so I know it is the indo. Looking for options.
