cluster headaches
"Imitrex in any form is the Best med for Cluster headaches by far. High flow oxygen at first twinge, and the pill at the onset (even if you think it might hurt) Most effective. You all know how fast they come on. Usually work immediately unless late in a cycle. I too wish you could take more than twice in a 24 hr period. After suffering for almost 20 yrs with no medicine at All. For these crippling things. I have tried all Imitrex types, injections ,pills, nasal sprays. Injections are fast but so very expensive and painful as well. Nasal spray is nauseating for me, the pill form has always worked well if taken at the very BLINK of headache. Because of price and insurance restrictions I would wait to take the medicine. Not anymore."
