Abstract: | Abstract: Chronic refractory daily headache is a relatively common problem in the Australian population. Several million working hours per year are lost due to this illness. Generally not responding to conventional therapies. We treated 22 such patients diagnosed as severe refractory migraine and/or mixed tension headache at our multidisciplinary pain management center. Before inclusion to our study, they received maximal medical management, which included cognitive behavior therapy, but failed to respond. These patients received between 30 and 100 units of botulinum toxin type A. Our study showed 84% (19 of 22) achieved significant improvement in their pain complaint. There was significant reduction of medications particularly opioids. The duration of pain relief ranged from 1 to 6 months. Repeat injections were necessary in several of the patients. There were minor complications but these reversed spontaneously without further treatment. |
