cluster headaches
"This is a miracle for me. Cluster headaches would put me out of commission for 2 days. Imitrex gets rid of the intense pain of my eye feeling like it might pop out of my head! The first few times I took it I had side effects of the heavy feeling on my chest and in my muscles after 3x I can take with no side effects. I've only taken it 5x  but still working great."
