Thanks to all! I have had MRI's and CT scans that don't show anything, ( good and bad right? ).
I asked the doctor if these were cluster and she said possibly. She is leaving the practice for another position so I will need to find a new Neuro anyway.
It is one headache, that lasts 3 days, about every 45 days. I have gone as long as 5 months without but this is rare. I do get migraines in between. I can always tell the difference because it escalates fast, I become very nervous, and the triptans I use sometimes for migraine don't affect it much at all. It can really help my migraine. I am 8 years post menopause so it is not my cycle. On one occasion it went away very quickly, I was in a car knelling in the back seat in horrid pain. I was hyperventilating and I sprayed biofreeze all over my face and breathing in the scent burned my nose but suddenly it was gone. I have tried to repeat this to no avail. On another desperate occasion I decided to breathe my oxygen for 30 minutes instead of 15. It eased up and I feel asleep. It did return but I had a few hours of peace. Let me tell you by day 2 I am hoping to leave this earth. When it is finally over I am happy to be still alive with my family but at times I want it to end so badly.......
I have autonomic dysfunction so I am afraid to try the mushrooms or LSD as I can have odd and severe reactions to any medication. Scary BP drops and other things.
