What Happens When You Throw Your Back Out? And What To Do Next

Hi, I’m Kat, physiotherapist and co-founder of Lake Therapy. If you’ve ever experienced that sudden, sharp pain in your lower back and thought, “I’ve thrown my back out”, you’re not alone. It’s one of the most common things we hear in clinic, and it can feel quite alarming when it happens. When you throw your back out, it often comes on quickly and can make even simple movements feel difficult. The good news is that, while it feels serious, most cases improve well with the right approach and guidance.

If your back keeps going, our page on back pain treatment in Farnham explains how we can help. You might also like my exercises for lower back pain relief.

What Does It Mean to Throw Your Back Out?

When people say they’ve thrown their back out, they’re usually describing a strain or irritation in the muscles or ligaments of the lower back.

This can happen when the tissues are overloaded, often through movement that the body wasn’t quite prepared for.

Common Symptoms When You Throw Your Back Out

You might notice:

• Sudden pain in the lower back
• Muscle tightness or spasms
• Difficulty standing fully upright
• Reduced ability to bend or move
• Pain when walking or changing position

Although it can feel intense, it doesn’t always mean there is serious damage.

Why You Might Throw Your Back Out

Sudden or Awkward Movements

Twisting, bending, or lifting in an unexpected way can overload the tissues in your back.

Improper Lifting

Lifting something heavy without support from your legs and core can place extra strain on the lower back.

Poor Posture Over Time

Spending long periods sitting or standing in one position can gradually affect how your body moves.

Reduced Strength or Support

If the muscles around your core and hips aren’t working effectively, your back may end up doing more than it should.

What To Do After You Throw Your Back Out

Stay Calm and Rest Briefly

Pause and avoid movements that aggravate your pain, but try not to stay completely still for long periods.

Use Ice Then Heat

Ice can help in the early stages, followed by heat to relax the muscles.

Keep Moving Gently

Small, comfortable movements help prevent stiffness.

Try Light Stretching

Once pain settles slightly, gentle stretching can support recovery.

When to Seek Help After You Throw Your Back Out

It’s worth getting support if you notice:

• Pain lasting more than a few days
• Difficulty moving or standing
• Pain spreading down the leg
• Numbness or tingling

Early guidance can prevent longer-term issues.

Getting through the first few days

Those first couple of days can be the hardest. Here are a few things that usually make them easier.

• Find a comfortable resting position. Lying on your back with your knees bent over a couple of pillows, or on your side with a pillow between your knees, often helps.
• Get up and walk little and often. A few minutes every hour or two keeps your back from stiffening up.
• Roll onto your side first when getting in and out of bed, then push yourself up with your arms.
• Avoid heavy lifting and long spells of sitting until things start to settle.
• Use pain relief if you need it, as advised by your pharmacist or GP, so you can keep moving.

Most people notice things easing day by day. If you’re not improving, or your back keeps going again, that’s when a physio can really help.
