Hi,i totally relate to your suffering.I was diagnosed with Hemicrania Continua in July this year.Indometacin is a lifeline and will assist you.Also as a backup you may have a nerve block in your Greater Occital nerve,it works for some and not for others.I think you will find relief in the indometacin and the other drug you are on sounds like a preventive tab.If you are having no luck a few months from now you may have multiple nerve blocks,which are powerful!
This migraine is a nightmare,i have had it for coming up 2 years and it is continual.Mine has been extremely aggressve and i have 12 injections into various nerves over the past 3 months and i am currently on Pregablin-150x twice daily and indometacin 75mg-x3 daily so i hope for some relief.
Good luck with everything
and if you need some support please respond.
All the best,
