Acute Back Pain: A Physio's 7-Step First 24-Hour Action Plan
Staggeringly, over 60% of people will experience an episode of acute low back pain in their lifetime. The onset can be as daunting as it is common.
When sharp, sudden pain strikes, you're faced with urgent questions: What's wrong? How long will this last? What should I do right now?
As a Physiotherapist, I've seen how the first 24 hours are critical. This guide provides a step-by-step action plan to regain control, calm your nervous system, and create the optimal environment for your body to begin healing—regardless of the specific cause of your pain.
Key Takeaways: Your First 24 Hours with Back Pain
- Calm Your Nervous System First: Pain is a threat signal. Deep breathing is your most powerful tool to dial it down.
- Find Your "Pain-Free" Position: Comfort is king initially. Don't force a "correct" posture if it hurts.
- Move Smart, Not Hard: Gentle movement facilitates healing, but let your pain be your guide.
- Address the Root Cause Later: Initial focus is on pain control. Professional assessment is key to long-term recovery.
The 7-Step Acute Back Pain Action Plan
Step 1: Find a Comfortable Position
Your first priority is to find a position that minimises your pain. This can be tough, but wriggle around until you find what's most tolerable. Forcing a "textbook" posture can often make things worse if it's not right for you in this moment.
Positions to try:
- Lying on your back with knees bent and feet flat
- Lying on your back with calves on a chair (knees and hips at 90 degrees)
- Lying on your side with a pillow between your knees
- Lying on your stomach (you can place a thin pillow under your hips)
- Sitting and leaning forward onto a table with your arms crossed
- Very slow, gentle walking
The Goal: A position that allows you to relax, which is crucial for the next step.
Step 2: Practice Deep Breathing to Calm Your Nervous System
This is potentially the most important step. We must address the "software" (your nervous system) before we can effectively treat the "hardware" (your tissues).
Physio Insight: A New Understanding of Pain
Pain is not just a measure of tissue damage; it's your brain and nervous system's perception of threat. An acute injury triggers a primitive "fight or flight" response, heightening your entire system and amplifying pain signals.
The faster we can calm this heightened state, the faster we can decrease the pain experience itself. Deep breathing is the most direct way to signal safety to your nervous system.
Technique: Box Breathing
Box breathing uses a slow, cyclical pattern to cue your body into a state of safety and relaxation.
How to do it: Breathe in for 4 seconds → Hold for 4 seconds → Breathe out for 4 seconds → Hold for 4 seconds. Repeat. Stick with this for 5-15 minutes, or until you feel your body and mind begin to settle.
Step 3: Think Twice Before Reaching For Pain Medication
This is a conscious choice. Pain is your body's boundary system. While medication can provide necessary relief, especially for sleep, it also masks these boundaries.
The Risk: If you numb the pain and then move in a way your body isn't ready for, you can easily re-irritate the area and prolong your recovery.
The Bottom Line: You don't have to be a hero, but make it a considered choice. If you can manage your pain with breathing and positioning, you'll have a clearer picture of what your body can safely handle. But sleep and work are important, and pain medication can help.
Step 4: Use Heat Wisely (And Rethink Ice)
The traditional "ice or heat" debate needs a modern update based on how the body heals.
On Ice: While ice can numb pain, it also constricts blood flow—the very thing delivering healing nutrients and removing waste. It can mask your pain boundaries, similar to medication. I've detailed why I often advise against icing here.
On Heat: Heat promotes blood flow, but applying it directly to an acutely inflamed area can sometimes increase swelling and pain if you're not moving enough to clear that waste.
The Smartest Use of Heat: Apply heat to stiff areas around your pain. For example, if your lower back is locked up, placing a heat pack on your stiff mid-back or tight hips can "feed slack" into the painful area, helping it relax. This can also have a calming effect on your nervous system.
Step 5: "Feed Slack" by Mobilising Surrounding Areas
Acute back pain rarely happens in a vacuum. It's usually the final straw after hidden stiffness in other areas has altered how you load your spine.
The goal is to find and mobilise stiff joints and tight muscles above, below, and around your pain to create mechanical space for the irritated area to recover.
Primary Targets: Stiffness in the thoracic spine (mid-back/ribcage) and hips are the most common culprits.

How to Mobilise Your Hips:
Use a tennis or lacrosse ball, and remember: you don't need to push directly on the most painful spot. Work around it.
Step 6: Introduce Gentle, Respectful Movement
Once your pain is more manageable, it's time to move. Movement is crucial—it pumps swelling away from the area, prevents muscle atrophy, and stops tissues from stiffening up.
How to start:
- Short, slow walks around your house.
- Gentle pelvic tilts while lying on your back.
- Very slow and small cat-cow stretches on your hands and knees (if comfortable).
The Golden Rule: Let your pain be your guide. Movement should not significantly flare up your pain. Find the edge of your comfort zone and move just within it.
Step 7: Know When to Seek Professional Help
This 7-step plan can help you navigate the initial crisis, but it's not a substitute for a professional diagnosis.
You should see a Physiotherapist or doctor if:
- Your severe pain doesn't start to settle within 2-3 days.
- You experience numbness, tingling, or weakness in your legs.
- You have changes in bladder or bowel function (seek immediate medical attention).
- The pain keeps returning.
A professional can identify the specific source of your pain (e.g., irritated joint, disc issue) and create a targeted rehab plan to not only recover but also address the root cause to prevent future episodes.
Conclusion: You Are In Control
The first 24 hours of acute back pain can feel frightening and overwhelming. This 7-step plan gives you a structured way to take back control. By calming your nervous system, finding comfort, and introducing smart mobility and movement, you create the best possible environment for your body to heal.
Be patient with yourself. Listen to your body. You have more influence over your recovery than you might think.

Frequently Asked Questions
What is the single most important thing to do for acute back pain?
Step 2: Deep Breathing. Calming your heightened nervous system is the fastest way to reduce the perception of pain and create a window for other interventions to work.
Should I rest completely or try to move?
Absolute rest is rarely the answer. After the initial severe pain subsides (often 24-48 hours), gentle movement is crucial for recovery. The key is "respectful movement"—staying within a pain-free or minimal-pain range.
How long does acute back pain usually last?
Most simple acute back pain episodes start to improve significantly within a few days to a week. However, the timeline varies greatly depending on the cause, your previous health, and how well you manage the initial phase.
When is back pain a medical emergency?
Seek immediate medical attention if you experience loss of bladder or bowel control, significant leg weakness, numbness in the saddle area (groin), or if the pain is accompanied by a fever. These can be signs of serious conditions like cauda equina syndrome.
