Almost two in five painkiller users need medication just so they can go to work, a healthcare charity has said.

Nuffield Health warned that long-term use of potentially addictive drugs is "commonplace" after it found that 37% of people who use medication to treat pain say they require drugs to be able to work.

And a third of painkiller users are worried about their dependency on drugs, the charity said.

Half of the 3,100 people surveyed said they managed pain or injury with painkillers in the last year and, of these, a quarter said they take between five and 10 painkillers every day.

One in three people said they were taking strong medication, including codeine and tramadol, to manage their pain. A total of 7% are using even stronger opiates, including morphine and pethidine.

Experts at the charity said painkillers are often seen as an easy or cost-effective treatment option instead of treating underlying medical problems.

Manoj Krishna, consultant spinal surgeon at Nuffield Health Tees Hospital, said: "A lack of knowledge, or fear of treatment, can lead patients into long-term use of painkillers, often without a clear diagnosis by a specialist.

"This can be a very bleak existence, with patients becoming depressed, losing their jobs and often becoming dependent on the drugs. I regularly see patients who struggle to deal with drug addiction after their medical condition has been successfully treated."

"With advances in medicine, it is important that patients explore their options fully," he added. "Surgery, physiotherapy or an effective exercise programme may be more appropriate. In the 21st century in a country with a world-class health service, our patients in pain deserve a better deal."

A charity spokeswoman said that people who have concerns about reliance on painkillers should see their GP "urgently".

    Omega-3 fatty acids are crucial for keeping the immune system healthy - and warding off inflammation and chronic neck pain. During research at the <a href="http://www.pitt.edu/" target="_hplink">University of Pittsburgh</a>, 60% of participants experienced enhanced pain relief from eating more fish or taking fish oil supplements for three months.

Besides salmon, other fish that contain high levels of the essential EPA and DHA omega-3 fatty acids include halibut, tuna, trout, mackerel and sardines.

  • Cherries For Arthritis

    Cherries, like the other members of the berry family, contain high amounts of antioxidants called anthocyanins - the key compound to the cherry's pain fighting power. According to research by the <a href="http://www.agriculture.gov.ie/" target="_hplink">Department of Agriculture</a>, participants who ate 45 big cherries daily for 28 days reduced their inflammation levels significantly.

Anthocyanins contain antioxidants, anti-inflammatory and anti-diabetic properties.

  • Coffee For Post-Workout Pain

    If you ever wondered why over-the-counter painkillers contain caffeine, it's because coffee enhances the effects of common pain relief. It also acts as a natural pain reliever itself, particularly good for post-workout aches and pains. Researchers from the <a href="http://www.uga.edu/" target="_hplink">University of Georgia</a> discovered that patients who drank two cups of coffee after working out, reduced common post-workout aches and pains by almost 50%. Experts also claim that caffeine is good for a pre-workout boost too, as it has been proven to raise the body's pain threshold.

  • Sage For Sore Throats

    The humble sage is commonly used to treat throat ailments, like tonsillitis, mouth ulcers, gum disease, laryngitis, as well as other problems like headaches, bruises, bad memory and common menopause symptoms. Sage contains rosmarinic acid, which is absorbed into the body and acts as an anti-inflammatory agent, which soothes inflamed muscles. Add it to boiling water and make your own sage tea, or sprinkle it as a seasoning on your food.
