Image-conscious individuals looking to receive Botox treatment to reverse the physical signs of ageing could be interested in alternative uses for the substance.
According to ABC 7News, increasing numbers of US doctors are using the treatment to ease the pain of migraines among patients.
The rise in the procedure's popularity comes after the Food and Drug Administration approved the product's use in select medical instances.
Experts define chronic migraines as 15 or more headaches per month, with many people experiencing problems with other aspects of their life as a result.
Dr Jason Krutsch, pain management specialist at University of Colorado Hospital, said: "Patients are often at [their] wits' end often having tried multiple medications and injections, and Botox is often the last step and the saving grace."
This news comes after UK charity the Migraine Trust called for the government to allow the NHS to issue the injection for the relief of headaches for free.
