Botulinium Toxin
(Botox and Myobloc)

In addition to treating wrinkles, Botox and Myobloc are useful for treating chronic pain. The most common pain problem treated is resistant muscle spasms of the neck and shoulders or the back. Resistant headaches, either migraine or chronic tension headache, are also commonly treated with botulinium toxin.

Less common problems treated with Botox or Myobloc are piriformis syndrome or cervical dystonia (torticollis).
