cluster headaches
"I have suffered from cluster headaches for over 15 years and have tried almost everything offered by hospitals and over the counter. I recently was given Imitrex in a nasal spray by my doctor and as long as your nasal passage is clear I have found that about five to ten minutes after you taste it in your throat the headaches go away. It is the best medicine I have ever come across for cluster headaches and my days and nights are much better because of it."
