Slip Disc Myths: Does Bed Rest Help?

"Lie flat for two weeks and don't move." Many people with a slipped disc are still given this advice by family, friends and sometimes professionals. It made sense once. Research since then has shown that, for most people, long bed rest makes back pain recover more slowly.

What a "slip disc" actually is

The discs between your vertebrae don't slip out of place. A disc has a tough outer ring and a softer centre. In a disc bulge or herniation, part of the disc pushes outwards and can irritate a nearby nerve. That irritation can cause sciatica: pain, tingling or numbness travelling down the leg.

Many disc bulges shrink and settle by themselves over weeks to months. Scans of people with no back pain at all often show disc bulges too, so a bulge on an MRI doesn't always explain your pain.

Myth 1: Bed rest heals the disc

Long bed rest leads to stiffness, weaker muscles and slower recovery. A day or two of taking it easy during a bad flare is fine. After that, staying gently active is better for most people: short walks, changing position often, and simple exercises your physiotherapist gives you.

Myth 2: You must never bend again

Your spine is built to bend. After a disc injury, you may need to bend less for a while and build back up gradually. Avoiding bending forever tends to make the back stiffer and more sensitive.

Myth 3: A slip disc always needs surgery

Most people with a disc herniation get better without surgery. Surgery is considered when there is severe or worsening nerve weakness, loss of bladder or bowel control, or pain that hasn't improved after a proper course of non-surgical treatment.

Myth 4: A belt should be worn all the time

A lumbar belt can give short-term comfort for specific tasks, like a long journey. Worn all day for weeks, it can let your own supporting muscles weaken. Use one only if your physiotherapist recommends it, and for limited periods.

What actually helps

• Staying as active as pain allows
• Positions that ease leg pain, which your physiotherapist can identify
• Gradual core and hip strengthening
• Manual therapy and, in some cases, traction to settle symptoms
• Pain relief advised by your doctor or pharmacist so you can keep moving

Go to a hospital the same day if you have numbness between the legs or around the back passage, new trouble passing urine or controlling your bowels, or weakness in both legs. These can be signs of cauda equina syndrome, a medical emergency.
