Migraine Prevention
"I had migraines for years. I tried Imitrex and similar meds but ended up with rebound headaches. It was a vicious cycle. Narcotic meds also did not work. 

Botox was a miracle for me. Within two weeks my migraines had disappeared entirely!  The Botox lasted for 4-6 months. 

I changed neurologists though last month and he had a different method of injection, using twice as much Botox (200 units instead of 100).  Two days later I developed horrible neck pain that progressed from sore to being barely able to hold my head up. I could not look down, bend, brush my teeth, or even turn my head. My head felt as if it weighed 200 pounds. Doctor said it would go away in 2 weeks!  10% of folks get this &quot;side effect.&quot;  I am still suffering."
