Pain is one of the most common reasons people seek physiotherapy. It can affect how you move, sleep, work, exercise, and manage daily activities. Pain may begin after an injury, develop gradually from repetitive strain, or persist longer than expected. For a broader overview of injury and recovery topics, visit our conditions guide. For specific treatment strategies, see our Pain Management guide.

Pain can come from muscles, joints, ligaments, tendons, nerves, or other body structures. However, pain is also influenced by sleep, stress, previous injuries, activity levels, and general health. This page explains what pain is, the main types of pain, common causes, and when physiotherapy may help. You can also learn more about nerve pain, chronic pain, and common presentations such as lower back pain.

Pain Symptoms and Common Causes

• Pain is a protective warning signal from the body.
• Pain can be acute, persistent, nociceptive, neuropathic, or mixed.
• Not all pain means serious tissue damage.
• Nerve pain often feels burning, shooting, tingling, or electric.
• Exercise, education, and physiotherapy often help recovery.

What Is Pain?

Pain is an unpleasant sensory and emotional experience linked to actual or potential tissue damage, or something that resembles it. In simple terms, pain is the body’s protection system. It aims to alert you to injury, overload, or irritation so you can respond and recover.

Pain and tissue damage do not always match perfectly. Some minor injuries can feel very painful, while some significant injuries may cause surprisingly little pain at first. That is why an assessment can help clarify what is driving your symptoms. You can also read our What Is Pain? FAQ for a simple overview.

Why Does Pain Feel Different for Everyone?

Pain feels different because it is influenced by biological, psychological, and lifestyle factors. Sleep quality, stress, previous injury, general health, fitness, and fear of movement can all affect how pain is experienced.

As a result, two people with similar injuries may report very different pain levels. This does not make the pain less real. It shows that pain is shaped by the whole person, not just the sore body part.

What Are the Main Types of Pain?

Nociceptive Pain

Nociceptive pain comes from irritated or injured tissues such as muscles, ligaments, joints, tendons, or bones. It is often described as aching, throbbing, or sharp and tends to be localised.

Common examples include muscle strains, knee pain, and shoulder pain.

Neuropathic Pain

Neuropathic pain occurs when a nerve becomes irritated, inflamed, compressed, or damaged. It often feels burning, tingling, shooting, electric, or numb.

You can read more in our guides to nerve pain and sciatica.

Persistent or Chronic Pain

Persistent pain usually lasts longer than three months or continues beyond expected healing time. In these cases, the nervous system may become more sensitive, which can increase how strongly the body reacts to movement or load.

For more detail, see our chronic pain FAQ.

Is Pain Always a Sign of Damage?

No. Pain is a warning signal, but it does not always reflect the exact amount of tissue damage. Some painful conditions are not serious, while some serious conditions may not feel severe at first.

That is why symptoms need context. A physiotherapist may assess your injury history, movement, strength, nerve signs, aggravating factors, and recovery pattern before explaining the likely cause of your pain.

Common Causes of Pain and Injury

• Sudden injuries such as falls, twists, lifting incidents, or sporting accidents.
• Overuse or repetitive strain from work, training, or daily activity.
• Joint irritation, stiffness, or inflammation.
• Nerve compression, irritation, or sensitivity.
• Rapid increases in exercise or training load.
• Reduced strength or conditioning after inactivity.

How Is Pain Treated?

Pain treatment depends on the cause, severity, irritability, and stage of recovery. Many people improve with a combination of activity modification, exercise, manual therapy, education, and a gradual return to normal activity. For more strategies, see our Pain Management page.

Physiotherapy may help by improving movement, restoring strength, and building confidence with daily tasks, work, and sport. Treatment may include manual therapy, strength training, and personalised exercise programs.

When Should You Seek Professional Advice?

You should seek professional advice if pain is severe, worsening, lasting longer than expected, or limiting work, sleep, exercise, or daily activities. Early assessment may help identify the cause and guide the right recovery plan.

Seek urgent medical attention if pain follows major trauma, causes breathing difficulty, includes loss of bladder or bowel control, or occurs with fever or unexplained weight loss.

What to Do Next

If pain is preventing you from moving comfortably or returning to normal activities, a physiotherapy assessment may help identify the likely cause and guide your recovery plan.

FAQs

What causes pain?

Pain can result from injury, inflammation, muscle strain, joint irritation, nerve compression, overload, or overuse. Stress, sleep, conditioning, and previous injuries can also affect pain levels.

Is pain always a sign of serious injury?

No. Pain is a warning signal, but it does not always match the severity of tissue damage. Some minor conditions can be very painful, while some significant injuries may hurt less than expected at first.

What does nerve pain feel like?

Nerve pain often feels burning, shooting, electric, tingling, or numb. It may travel along the arm or leg and is commonly linked to nerve irritation or compression.

When should I see a physiotherapist for pain?

If pain persists, worsens, interferes with movement, affects sleep, or limits daily activity, a physiotherapy assessment may help determine the cause and guide treatment.
