"I used my first Sumavel Dosepro last night. I woke up about 11pm with a splitting migraine. My migraines last between 12 to 16 hours. I took the shot and within ten minutes the headache was gone! I don&#039;t mean dulled, I mean gone! This was a MIRACLE in my book. The injection was a little painful. I&#039;m good with that! Finally, quick relief for my migraines which have plagued me for over 43 years!"
