Bed rest is the key to recovery

Recommendations have flipped over recent years between staying in bed or staying active, and a 2010 Cochrane review suggested that the margin between these pieces of advice is closer than once thought.


But, overall, studies show that being active has an edge over bed rest, and current clinical guidelines favor activity and exercise. One thing's for certain - prolonged bed rest can lead to muscle atrophy and deconditioning, which can make getting back on your feet a greater challenge.

Sit up straight to stop the pain

I always tell my patients to listen to their bodies, and in certain back conditions, sitting up straight may be even more painful than bending because of added pressure on the lumbar spinal nerve roots. Conversely, a patient may get some relief lying on one side in the fetal position.


There hasn't been much scientific evidence directly linking posture to developing back pain, but it makes sense that posture can put pressure on different parts of your back. And if you're always slumped to one side, some muscles may become weaker than others and therefore more susceptible to strain or damage. If spinal supporting muscles weaken, it can also affect the position of your spine, contributing to back pain.

Your diet may affect your heart but it won't affect your back

I've seen quite a few overweight patients lose their back pain when they lost weight. Of course, the converse also applies. Carrying extra weight, especially in the gut, can strain your back and increase lumbar lordosis, an excessive inward curvature of the spine. Weight gain also causes some pregnant women to develop low back pain. And obesity speeds up lumbar disc degeneration that often occurs with aging.


A recent study showed that even adolescents who are overweight are susceptible to low back pain and disc degeneration, and an elevated body mass index (BMI) was significantly associated with increased severity of disc degeneration. Are you at risk? Calculate your BMI to find out.

You?ll need to invest in orthotic shoes

Probably not - although orthotic devices can help in some cases, like when one leg is shorter than the other. But you do have to be mindful about which shoes you wear. It's better to forget the flip flops and opt for good ankle support because strains in your foot and ankle muscles can throw off your gait and further stress your back.


High heels can aggravate low back pain, partly because - like extra abdominal weight - they can increase lumbar lordosis. It's important that the shoes are cushioned and firm because they absorb more impact than a flimsy pair.

Get the firmest mattress you can find

Several studies suggest that people who suffer from low back pain actually benefit more from a medium-firm mattress. Why? If a mattress is too firm, it won't support the body evenly and may cause discomfort at the heaviest points like hips and shoulders. If the mattress is too soft, a sleeper could sink into the bed and have a harder time moving, which could cause stiffness and pain come morning.


Having a slightly softer mattress places less compression on your body and may grant you a better night's sleep.

There are lots of ways to treat back pain, but the only cure is surgery

Unless your pain is unrelenting and no form of treatment seems to work, or you develop a serious neurological deficit - such as a foot drop - you shouldn't rush to surgery. Many common back problems - even those that cause severe pain - resolve themselves over time.


And not everyone that undergoes surgery is happy with the end result. A 2009 survey of almost 1000 consumerreports.org subscribers who had undergone surgery for low back pain found only 60 percent said they were completely or very satisfied with the results of their operation. In comparison, 82 percent of the people who had hip or knee replacement surgery in a 2006 survey said they were completely or very satisfied with the results.

If you don?t have associated symptoms in your legs, you should generally wait a minimum of 6 to 12 weeks before making your decision.
