Millions of Americans suffer migraines, but relief may be found in Britain. Doctors there claim to have a new procedure that can stop the debilitating headaches.

A cosmetic surgery for wrinkles is now be being used by British doctors to stop migraines.

One plastic surgeon says it involves a muscle in the forehead that is removed to reduce frown lines.

"We discovered that when taking out this particular muscle, there were over the years more and more patients who told us that, ‘By the way my migraine had improved,’" said Dr. Thomas Muehlberger.

It's called the corrugator muscle, which lies between the branches of a nerve. Doctors say by taking out the muscle pressure on the nerve is released, and with it the cause of the headaches.

But it's not for everyone. To find out if a patient is a candidate doctors first use another wrinkle fighter — Botox — to paralyze the muscle. If in a couple of weeks the patient feels migraine relief, they can have the surgery.

The procedure was discovered in the U.S., but doctors overseas are the first to offer it on a widespread basis and a new clinic has just opened in London.

Small studies have shown the treatment is effective.

"It changed my whole life, basically,” said Ricki Nerreter, who had the procedure done. “It was completely different afterwards. I had no migraines."

Still, many experts aren't completely sold.

"One of the precursors to the treatment is to have a Botox injection to see if that would actually have an effect on headache,” explained headache specialist Dr. Andy Dowson. “When we give Botox in headache patients we tend to give it in a much more wide area than just corrugator, so I think the jury would be out from my perspective.”

We should have a verdict after many more procedures are done. If it's favorable we'll likely see the surgery move to America.
