That sounds like classic cluster headache symptoms. My heart goes out to you.

Vasoconstrictors help me but they have their own set of worrisome issues.

There are a lot of newer preventative medications on the market for migraines that may work and I think at least one that's got an approval for cluster headaches. They didn't help me but they may help you.

One thing I'd suggest is to try to find what if anything triggers your episodes and remove those. These could be food, food additives, medications, alcohol etc. in my case, anything with vasodilation properties can trigger or worsen a headache.

Some people seem to have issue with things that elevate serotonin or histamine. Hopefully you can narrow down your triggers.

I hope you feel better soon
