Cluster Headaches
"I have severe and debilitating cluster tension headaches. I had a problem with doctors trying to treat me for migraines and I DON&#039;T HAVE MIGRAINES. This is the only medication that seems to work. My headaches seem to stem from my neck. This medicine totally relieves my neck pain and may also be helping my sciatica. Sleepy.... YES. However I usually have trouble sleeping from the headaches and neck pain, so I&#039;m not complaining."
