Psychosomatic effects of stress: why emotional tension causes back pain and muscle tightness

When the brain perceives a situation as dangerous, the body prepares for rapid action. The heart rate increases, breathing becomes faster, blood flow changes, and the muscles tense. This is a natural protective response that prepares the body to defend itself.

Once the stressful situation is over, the body gradually returns to its normal state: the heart rate and breathing slow down, and the muscles relax.

The problem arises when stress becomes chronic. Constant emotional tension and sleep problems keep the body in a state of continuous readiness. Muscles contract more frequently and remain tense for longer periods.

This is most often noticeable in the neck, shoulders, back, and jaw muscles. At the same time, a person may not be aware of the tension: they may raise their shoulders while working, clench their teeth, hold their breath, or constantly keep their abdominal muscles tense.

Prolonged muscle overexertion can lead to muscle fatigue, soreness, and a feeling that certain areas of the body have become “rock-hard.” Sleep deprivation and persistent anxiety can further intensify this state: they exhaust the nervous system, making it more reactive to pain signals. As a result, pain may persist or become more intense even when the person is no longer in a stressful situation.

How to tell whether stress is making your muscle pain worse

Several patterns can help identify a connection between stress and physical symptoms:

• Pain or tension becomes worse after emotionally difficult events, prolonged work without breaks, or periods of persistent anxiety.
• After rest, adequate sleep, or a reduction in stress levels, the symptoms become less intense.
• Along with back pain, other signs of physical tension may appear, such as teeth clenching, headaches, shallow breathing, or difficulty falling asleep.

An important nuance: when nerve structures in the lower back are irritated, pain can radiate from the lower back into the buttock or leg. Sleep deprivation and severe stress can increase its intensity.

The next step is therefore to determine whether the pain has signs of a neurological origin. This affects the further treatment approach: whether addressing muscle tension and stress is sufficient, or whether examination and treatment by a neurologist are needed.

Why massage makes you feel better, but the pain comes back

Massage can temporarily reduce the sensation of muscle tension and pain. A person may feel more relaxed, movement may become easier, and discomfort may decrease.

However, if the symptoms return a few hours later or the following day, this may indicate that the factors contributing to the tension are still present. For example, a person may continue working without breaks, sleep only a few hours a night, constantly clench their jaw, or remain in a state of anxiety. In this situation, repeating massage alone is not enough. It is important to identify the factors that are maintaining the tension and address them directly.

How stress changes behaviour and maintains pain: fear of movement

After experiencing several episodes of pain, a person may begin avoiding movement. They may walk less, stop exercising, bend more cautiously, or try to keep their back in a “correct” position.

This creates an additional problem: physical endurance decreases, muscles become less accustomed to physical load, and fear of recurring pain increases attention to every sensation. In chronic pain, this mechanism has a specific term – fear of movement and activity avoidance (kinesiophobia).

This is why current recommendations for low back pain include maintaining physical activity and addressing psychological factors that may interfere with recovery.

What symptoms can accompany stress-related muscle tension

• Neck stiffness after a working day;
• Pain or a feeling of heaviness in the shoulders;
• Discomfort between the shoulder blades;
• Tension in the jaw muscles and teeth clenching;
• Headaches;
• Dull or aching back pain;
• A feeling of physical fatigue after an emotionally stressful day;
• Worsening symptoms after insufficient sleep.

Which symptoms require a neurologist’s consultation

Back pain can be associated with irritation or damage to nerve structures. Possible warning signs include:

• pain radiating down an arm or leg;
• numbness, tingling, or reduced sensation;
• weakness in a limb;
• changes in gait or impaired coordination;
• changes in reflexes identified by a doctor during an examination.

Particular attention is required when loss of bladder or bowel control occurs together with back pain, especially if these symptoms develop suddenly. This combination requires urgent medical assessment.

The goal of a neurologist’s consultation is to determine the source of the symptoms and assess whether there are signs of nervous system involvement.

The doctor takes a medical history, clarifies the nature, location, and distribution of the pain, and assesses muscle strength, sensation, reflexes, coordination, and other neurological functions. Based on the examination, the doctor determines whether additional diagnostic tests are needed.

How psychotherapy can help in this situation

In chronic pain, psychotherapy can help address factors that maintain or intensify symptoms. One of the most extensively studied approaches is cognitive behavioural therapy (CBT).

How it works – an example: A person experiences lower back pain and begins avoiding bending, exercise, and other movements because they are afraid of damaging their spine. Physical activity decreases, the body becomes less accustomed to physical load, and each new episode of pain causes even more anxiety. A psychotherapist helps the person understand this cycle, address their fears, and gradually return to safe physical activity.

Anxiety, persistent emotional tension, sleep problems, and responses to traumatic events can also be addressed. When these factors decrease, it becomes easier for the nervous system to shift from a state of constant readiness to a calmer state.

Self-regulation methods: biofeedback and neurofeedback

A psychotherapist may also recommend methods that help train physiological self-regulation. One of these is neurofeedback and biofeedback (biological feedback).

During a session, special sensors record certain physiological parameters, such as heart rate, breathing, or muscle tension. The person can see these changes in real time and learn to influence them through specific exercises.

For example, when there is persistent tension in the neck muscles, their activity can be monitored while the person trains their ability to relax them. Similarly, during biofeedback, breathing and heart rate can be monitored to help a person learn to reduce physical tension more quickly during stressful situations. Over time, the person becomes better at recognising their own responses to stress and learns to regulate them independently.

Which approach is right for your situation

At Doctor Sam, a patient can start with a neurologist’s consultation to assess the physical and neurological aspects of their symptoms. If the pain is associated with persistent muscle tension, the doctor may recommend appropriate physical therapy methods or massage.

If anxiety, chronic stress, emotional exhaustion, or sleep problems play a significant role, a psychologist or psychiatrist may become part of the treatment process. Biofeedback / neurofeedback may be recommended to develop physiological self-regulation skills.

There is no need to wait until pain, tension, or sleep problems begin to affect your work, rest, and everyday life. The sooner the underlying cause of the symptoms is identified, the easier it is to choose an appropriate treatment approach and prevent the problem from becoming long-lasting.
