Cluster Headache. It's also not working.

I am suffering from left sided Headache with redness of left eye and left side blocked nose for 7 years. The Headache is very painful lasting for 2 hours if I am not taking any medicine. Only Sumatriptan 85mg and naproxen 500 mg tablet 2 number at a time help to reduce the Headache in 45 min. Approx 7 neurologist I have visited but changes of medicine not helping me. I have tried Practine, varapamil 120, propranolol but nothing is curing my Headache. Please help. Now for last 1 year it's continued and not stopped. Every 2 nd day the pain is coming and after 2 days it's not happening. Previously it will comes once in a year. But now it's continuing for last 1 year. Last I have tried indomethacin but it's also not working.
