Migraine
"I have been using Imitrex 5mg injections for several years as an emergency migraine  abortive. While it did instantly relieve the head pain and nausea, I had to then wait out 30-45 minutes of side effects. Those side effects were: upper jaw pain, and overall body aches (like when you have the flu) such as super sensitive skin, even my hair hurt. But for a long time this was the only option available to me through insurance, and the side effects were more bearable than the migraine. But recently the injection stopped working, and I ended up having to go to the ER. Now I have been given Zomig nasal spray. I have not had a reason to try it yet, but am worried about side effects."
