Pain: Types, Causes and When to Seek Help
Pain can affect movement, sleep, work, exercise and everyday activities. It may start after an injury, develop gradually with repeated loading, come from an irritated nerve or continue after normal tissue healing. Pain is real, but its intensity does not always show how much tissue damage is present.
This guide explains common pain types, possible causes, warning signs and how physiotherapy may support recovery. For a detailed treatment overview, visit our Pain Management guide. You can also explore our broader conditions guide.
Pain at a Glance
- Pain is a personal sensory and emotional experience.
- It may be acute, persistent, nociceptive, neuropathic, nociplastic or mixed.
- The amount of pain does not always match the amount of tissue damage.
- Sleep, stress, health, activity levels and previous experiences can influence pain.
- Assessment, education, appropriate movement and gradual rehabilitation may support recovery.

What Is Pain?
Pain is an unpleasant sensory and emotional experience linked to actual or potential tissue damage, or an experience that resembles it. It is influenced by signals from the body and how the brain interprets possible threat or danger.
Pain often helps protect you after injury. However, it is not a direct damage meter. A small injury can feel severe, while a significant injury may initially cause little pain. Persistent pain may also continue after tissues have healed because the nervous system remains sensitive or protective.
Our What Is Pain? FAQ provides a shorter overview.
Why Does Pain Feel Different for Everyone?
Pain differs because many factors shape the body’s protection response. These factors may include the injury or condition itself, sleep quality, stress, previous pain experiences, general health, physical conditioning and confidence with movement.
Two people with similar scan findings or injuries may therefore report very different symptoms. This does not make either person’s pain less real. Instead, it shows why assessment and treatment need to consider the whole person rather than only the sore structure.
What Are the Main Types of Pain?
Nociceptive Pain
Nociceptive pain comes from irritated, overloaded or injured body tissues. These may include muscles, joints, tendons, ligaments and bones.
It often feels aching, throbbing, tender or sharp. Examples include a muscle strain, joint sprain or tendon injury.
Neuropathic Pain
Neuropathic pain occurs when a nerve is irritated, compressed, inflamed or damaged.
Symptoms may include burning, shooting, electric pain, tingling or numbness. Read more about nerve pain and sciatica.
Nociplastic Pain
Nociplastic pain involves altered pain processing without clear evidence that ongoing tissue damage or a nerve lesion fully explains the symptoms.
The nervous system may become more responsive, causing ordinary movement, touch or loading to feel more painful than expected.
Persistent or Chronic Pain
Persistent pain usually lasts longer than three months or continues beyond the expected tissue-healing period.
It may include nociceptive, neuropathic or nociplastic features. Visit our chronic pain guide for more information.
Referred Pain
Referred pain is felt in an area away from its original source. For example, an irritated joint or spinal structure may produce symptoms in another part of the body. A clinical assessment can help distinguish referred pain from local tissue pain or nerve-related symptoms.
Mixed Pain
Many people have more than one pain mechanism. For example, an injury may initially involve tissue irritation, followed by nerve sensitivity or a more protective nervous-system response. Treatment should match the main factors influencing the person’s current symptoms.
Is Pain Always a Sign of Damage?
No. Pain can indicate tissue irritation or injury, but it does not precisely measure damage. Symptoms depend on how the nervous system interprets information from the body in the context of your health, environment and previous experiences.
This means that movement may sometimes feel painful without causing further harm. However, pain should not simply be ignored. Assessment may help determine whether activity is safe, whether loading should change and whether another health professional should become involved.
What Commonly Causes Pain?
- Falls, twists, impacts, lifting incidents and sporting injuries.
- Muscle, tendon, ligament or joint overload.
- Repetitive work, training or daily activity.
- Nerve irritation, compression or sensitivity.
- Rapid increases in exercise or training load.
- Reduced strength or conditioning after illness or inactivity.
- Inflammatory, medical or systemic health conditions.
- Persistent nervous-system sensitivity after an earlier injury.
What Factors Can Make Pain Feel Worse?
Pain may become more noticeable when several physical and lifestyle factors occur together. These can include poor sleep, stress, illness, low activity levels, sudden workload changes, reduced confidence with movement or repeatedly pushing through highly irritable symptoms.
These factors do not mean the pain is imagined. They influence how sensitive and protective the nervous system becomes.
How Does a Physiotherapist Assess Pain?
A physiotherapist may ask about when the pain started, where it is felt, how it behaves and which activities affect it. The assessment may also examine movement, strength, joint function, nerve signs, balance and task-specific capacity.
The goal is not only to identify a sore structure. The physiotherapist also considers contributing factors, warning signs, current activity demands and the safest pathway back to work, exercise or daily activities.
How May Pain Be Managed?
Pain management depends on the likely cause, symptom irritability, health history and stage of recovery. No single treatment suits every person.
A management plan may include:
- clear education about the likely pain mechanism;
- temporary changes to aggravating activities;
- gradual exposure to comfortable movement and loading;
- strength, mobility or conditioning exercises;
- sleep, pacing and workload strategies;
- manual therapy where appropriate;
- a personalised exercise program; and
- medical or specialist review when symptoms need further investigation.
See our full Pain Management guide for further information.
When Should You Arrange an Assessment?
Consider professional advice when pain:
- is worsening or not improving as expected;
- limits walking, lifting, work, sport or daily activities;
- repeatedly returns when activity increases;
- disturbs sleep or affects confidence with movement;
- includes burning, tingling, numbness or weakness; or
- has an unclear cause.
When Does Pain Need Urgent Medical Attention?
Seek urgent medical assessment when pain occurs with:
- major trauma or a suspected fracture;
- chest pain, difficulty breathing or sudden severe illness;
- new loss of bladder or bowel control;
- new numbness around the groin or saddle region;
- sudden or rapidly worsening weakness;
- fever with severe or worsening pain;
- unexplained weight loss or significant general illness; or
- symptoms that feel severe, unusual or medically concerning.

Pain FAQs
What causes pain?
Pain may result from an injury, tissue overload, inflammation, joint irritation, muscle strain, nerve irritation or a medical condition. Sleep, stress, general health, activity levels and previous pain experiences may also influence symptoms.
Is pain always a sign of serious injury?
No. Pain can occur with tissue injury, but its intensity does not always match the seriousness of the condition. Some minor problems feel severe, while some significant conditions initially cause little pain. Assessment helps place symptoms in context.
What does nerve pain feel like?
Nerve pain may feel burning, shooting, electric, tingling or numb. Symptoms may travel along an arm or leg and may occur with weakness or altered sensation.
What is the difference between acute and persistent pain?
Acute pain commonly starts with a recent injury, illness or irritation. Persistent pain lasts longer than three months or beyond expected healing time and may involve ongoing nervous-system sensitivity.
Can pain occur without ongoing tissue damage?
Yes. Pain can continue even when tissue damage does not fully explain the symptom intensity. This may occur when the nervous system remains sensitive or protective after an injury or prolonged period of pain.
When should I see a physiotherapist for pain?
Consider a physiotherapy assessment when pain persists, worsens, repeatedly returns or limits movement, sleep, work, exercise or everyday activities. Urgent or medically concerning symptoms require medical assessment.
What to Do Next
If pain is stopping you from moving comfortably or returning to normal activities, a physiotherapy assessment may help clarify the likely contributing factors and guide a suitable recovery plan.
A physiotherapist can assess movement, strength, nerve signs and activity demands. They can then explain which activities are safe, what may need temporary modification and how to rebuild capacity gradually.
