It’s off-label but I have been successful with 50 to 100 mgs of Trazadone. It absolutely just bandages the pain and doesn’t get rid of the migraine. However, it’s the only instant relief I have ever gotten after trying everything else under the sun. Midrin worked when I was younger but eventually stopped. My mom uses Imitrex with success. But after suffering from extended pain like you’re describing, I took a chance on using Trazadone for it and it worked!
