Pain
"I received an injection of this medicine because of a debilitating migraine which lasted for more than two weeks.

When this was injected I almost immediately started to feel CRAZY.

I wanted to leave the hospital immediately, even though my migraine was worse- not better. I actually WALKED home (hospital was nearby) but my right leg went numb &amp; I literally dragged it behind me all the way home.

This was followed by EXTREME anxiety, confusion and a full week of insomnia which I had to be treated for. 

Obviously, I had one of those &quot;rare&quot; reactions. However, a close friend later had a similar reaction to this medication and had to be put it a straight jacket following administration. 

So, these reactions, while rare, can be extreme."
