newby to this site, I am from oz and been suffering for about 9 years
6 to 10 months on and 7 months off .  Was 9 months into last cycle and tried botox injection, after 4 weeks cycle ended. Not sure wether botox worked or end of cycle. Has anybody else tried botox , and had success.? (Botox extremely expensive in Australia.)

PS Cycle has resumed and will probably try botox again, but would be good to know  if anyone else has had success.

The use of botulinum toxin in the management of various neurologic and non-neurologic disorders has grown considerably over the past decade. At the same time, new information regarding the mechanism of action of these toxins has evolved allowing for a greater understanding of the versatility of these agents. Although two types of botulinum toxin (type A Botox and type B Myobloc ) are commercially available in the US, most studies of the use of these toxins for the management of chronic pain and headache have been completed with type A. Data from open-label and retrospective studies as well as clinical practice suggest as strongly as possible that there is a role for these agents, especially Botox, in the management of several chronic headache disorders, including chronic migraine, chronic tension-type, cervicogenic, and cluster headache. Emerging data regarding the use of these agents for so-called "analgesic-rebound" headache also appear impressive; however, as of yet, no multicenter, randomized, controlled studies for any headache type have been published that confirm the results seen in noncontrolled studies. Nevertheless, the benefit that some patients experience from this agent is impressive, and this drug appears for many to modify the disorder in a very positive manner. In a similar fashion, data for other pain states are often restricted to open-label and case study approaches; however, clinical experience and some of the available studies (even small controlled studies) suggest a role for the toxins in the management of various chronic pain states, such as myofascial pain, low back pain, and neuropathic pain. One of the greatest challenges ahead for all interested in this area is confirming the benefit seen clinically through appropriately designed multicenter, randomized, controlled studies.

REVIEWERS' CONCLUSIONS: There is convincing evidence for the effectiveness of BoNT in the treatment of pain associated with cervical dystonia. Due to the frequent adverse effects predominantly observed with higher doses, the trade off in risk and benefit should be carefully considered in each case. For all other rare head and neck pain syndromes we found no [randomized controlled trials for] (CLUSTER HEADACHE, chronic paroxysmal hemicrania, trigeminal neuralgia) and only a few small sized trials (cervicogenic headache, chronic neck pain, temporomandibular disorders). We were therefore unable to draw any definite conclusions.
