migraine
"I tried Sumavel Dosepro for the first time approximately 3 months ago.  It does take away about 80-90% of the headache pain, but am left with a "sinus" feeling  headache that really hurts when I cough, sneeze or bend over, which is typical for me for a day after a migraine.  The injection sting feels a little like being snapped by a rubber band.  It didn't feel extremely painful to me. I do get a fairly intense burning sensation mostly along my scalp but to a lesser degree across the surface of my skin as well. My arms feel very heavy and it was frightening at first.  My biggest problem is that I get intensely sleepy and for about 20 minutes I feel like I'm operating in "slow motion"."
