Victoria Saxton has suffered from migraines for years.
For a long time -- she tried to manage the pain on her own -- with over-the-counter pain killers.
"And they work at first, so you take more and more - so I started taking them like they were candy."
It turns out she was making her pain worse.
Doctors diagnosed her with what's called a 'medication overuse headache.' "Only about 50% of people actually go and get and get a diagnosis. Because they think their doctor will send them away saying it's just a headache," says Wendy Thomas, Chief Executive of Migraine Trust.
British health experts say patients who take over the counter painkillers, including aspirin and ibuprofen, up to 15 days a month could be causing their headaches.
The National Institute for Health and Clinical Excellence is urging doctors to take a closer look at whether painkillers could be hurting their patients.
It's estimated one in 50 people get headaches from taking too much medication - and women are five times more likely to suffer than men.
"I had no idea what I was doing, I was in excruciating pain and just trying to help myself."
Victoria now has the help of a doctor and takes 4 pills a day - instead of ten - to manage her pain.
And she keeps a journal to track her progress.
