When pain does not go away after surgery
Surgery places a considerable strain on the body. Tissue is cut, nerves are stressed, and the healing process takes time. Pain in the first days and weeks after a procedure is therefore to be expected – it is part of the natural course of wound healing. In most cases, the symptoms steadily ease as recovery progresses.
In some patients, however, the pain persists or changes in character. If postoperative pain lasts longer than three months, specialists refer to it as chronic post-surgical pain (medical term: chronic postsurgical pain, CPSP). Studies show that, depending on the type of procedure, between 10 and 50 per cent of those operated on may experience longer-lasting symptoms – a topic that is receiving increasing attention in medical care.
Acute versus chronic postoperative pain
To better assess the need for further investigation, it is helpful to distinguish between acute and chronic pain.
Acute postoperative pain
- Occurs immediately after the procedure
- Is part of natural wound healing
- Usually subsides within days to a few weeks
- Generally responds well to standardised pain therapy
Chronic postoperative pain
- Persists for longer than three months after surgery
- May change in character and intensity
- Is often no longer in proportion to visible healing progress
- Affects daily life, sleep and quality of life
Possible causes of persistent symptoms
There are many reasons why pain can become chronic after surgery. Often, a combination of several factors is involved.
Nerve-related causes
In many procedures, minor nerve injuries cannot be completely avoided. If nerve fibres are irritated or severed during surgery, what is known as neuropathic pain may develop. Typical descriptions include:
- burning or stabbing
- electrifying, shooting
- accompanied by tingling or numbness
- sensitive to touch or temperature changes
Changes in the pain processing system
If a pain stimulus persists for a long time, nerve cells in the spinal cord and brain can change. This process is called "central sensitisation": the pain system reacts more sensitively, sometimes even to stimuli that would not normally cause pain.
Other possible factors
- Scar tissue and adhesions
- Muscular tension caused by protective postures
- Inflammatory processes in the surgical area
- Psychological stressors such as ongoing stress or anxiety, which can influence the experience of pain
When a pain medicine assessment can be useful
Not every pain after surgery requires a specialist assessment. There are, however, signs that should prompt consideration of a consultation with a pain medicine specialist or a visit to a pain clinic.
Possible indicators
- The pain persists for more than three months after the procedure
- The symptoms tend to increase rather than decrease
- Standard painkillers do not provide sufficient relief
- Burning, shooting or electrifying pain occurs
- Sleep, mobility or daily life are significantly impaired
- The pain spreads to areas outside the surgical site
- Numbness, weakness or restricted movement are also present
In such cases, early assessment is often helpful. The longer pain persists, the more complex its treatment can become – early recognition can help to limit chronification.
What happens during a pain medicine assessment
A pain medicine examination goes beyond a purely physical evaluation. The aim is to obtain as comprehensive a picture of the symptoms as possible.
Typical components
- Detailed consultation (medical history): course of the pain, previous treatments, accompanying symptoms, impact on daily life
- Physical examination: assessment of the surgical area, mobility and neurological functions
- Pain questionnaires: recording intensity, character and burden
- Imaging or neurophysiological investigations: where necessary, for example to assess nerve function
- Consideration of psychosocial factors: because pain is always seen in the context of a person's life situation
Based on these findings, an individual treatment plan is discussed.
Treatment options for chronic pain after surgery
Modern pain medicine takes a multimodal approach. This means that different elements are combined in order to relieve symptoms. Which measures are suitable in an individual case depends on the cause and the personal situation.
Drug therapy
- Classic painkillers such as non-steroidal anti-inflammatory drugs
- For neuropathic pain, certain antidepressants or anticonvulsants that can influence the pain system are sometimes used
- Topical applications, such as medical patches or ointments
Interventional procedures
- Targeted injections near nerve structures
- Infiltration of painful scar areas
- In selected cases, further procedures in specialised facilities
Physical and movement therapy measures
- Physiotherapy to improve mobility and muscle function
- Manual therapy, heat or cold applications
- Gradual build-up of physical activity
Psychological and educational components
- Pain education: understanding the mechanisms of chronic pain
- Relaxation techniques such as progressive muscle relaxation
- Cognitive strategies for coping with pain
These approaches complement one another and, in combination, can contribute to relief. Reliable promises of a cure cannot be given – however, many of those affected experience a noticeable improvement in their quality of life through structured pain medicine support.
What those affected can do themselves
Even without specialist treatment, there are ways to support your own healing process.
- Take pain seriously instead of simply "putting up with it"
- Keep a pain diary: when, how strongly, in which situation
- Pay attention to sufficient sleep, exercise and stress reduction
- Inform your treating doctor early on if symptoms do not subside
- Do not hesitate to seek a second opinion
Conclusion
Pain after a procedure is normal in the acute phase – but if it persists for months or changes, a careful assessment is advisable. A pain clinic or a pain medicine practice can help to identify causes and develop an individually tailored treatment plan. In many cases, acting early improves the prospects of noticeable relief.
