Overview
Pain in the belly does not always come from the stomach, bowel, liver or other organs. The belly wall (the muscles, tissue and nerves between the skin and the organs) can also hurt. Abdominal wall pain is a common but often overlooked cause of long-lasting belly pain. The most frequent form is anterior cutaneous nerve entrapment syndrome (ACNES), where a small nerve that passes through the muscle wall becomes pinched or irritated. Other causes include muscle strain, a hernia or scar-related pain.
Symptoms
Pain in a small, well-defined area of the belly wall, often on one side
Sharp, burning or "stabbing" pain, or a constant ache
Pain that worsens with movement, twisting, coughing, sitting up or tensing the belly muscles
Tender spot you can point to with one finger
No clear link with eating, bowel movements or vomiting
Skin over the area may feel unusually sensitive
Self-Care Tips
Having your pain recognised as real and understood makes a difference; ask for a clear explanation.
Stay active within comfortable limits and see your doctor if the pain changes.
When to See a Doctor
Seek medical care promptly if you notice: Sudden severe belly pain, a rigid belly, or pain with fever or repeated vomiting; A bulge or lump that becomes hard, painful or cannot be pushed back, especially with vomiting; Blood in stool, black stools, vomiting blood, unintended weight loss or persistent fever; Painful blistering rash on one side of the belly; Pain after an injury to the belly or a fall.
Why it happens
A nerve that supplies the skin of the belly can get squeezed where it passes through the muscle wall, causing sharp or burning pain. Past surgery, scars, pregnancy, injury, strong muscle strain, weight change or repeated movements may play a role, but sometimes there is no clear trigger. The pain is stimulated by movement of the belly wall, rather than by food or bowel habits.
How common it is
It is believed to be a notable cause of chronic belly pain, and many people have had extensive tests for organ disease before the diagnosis is made. It can affect all adult ages and is reported more often in women.
How it is diagnosed
The diagnosis is mainly clinical, meaning it is made by examination. In Carnett's sign, the doctor presses on the tender spot while you tense your belly muscles (for example by lifting your head or legs off the bed). If the pain stays the same or becomes worse, the cause is likely in the belly wall; if it becomes less, the cause is more likely inside the belly. Tests such as blood work, ultrasound or CT may still be done to rule out other conditions, particularly if there are red flags. An injection of local anaesthetic into the tender spot can both confirm the diagnosis and relieve pain.
Lifestyle and daily habits
Simple measures can ease the pain once other causes have been excluded.
• Use gentle heat (a warm, not hot, pack) on the area if it feels better
• Avoid movements and positions that clearly trigger the pain for a short while, but keep moving gently overall
• Avoid tight belts and waistbands over the painful area
• Physiotherapy can help, with exercises to strengthen and stretch the belly wall and posture
• Return to normal activity gradually as the pain improves
Diet
Diet does not cause or cure abdominal wall pain.
• There is no special diet for this condition
• A healthy weight reduces strain on the belly wall
• Avoid unnecessary food restrictions in the belief that food is the cause
Medicines
Medicines can help, but injection treatments are often the most effective. Your doctor decides what is suitable.
• Simple pain relievers may help in the short term; check safe use with your doctor
• Local anaesthetic injection at the tender spot may give relief and confirm the diagnosis
• Nerve pain medicines may be used when pain persists
• Strong opioid pain medicines are generally avoided in long-lasting pain of this type
Procedures and surgery
If simple treatment is not enough, a pain specialist may help.
• Trigger-point or nerve-block injections (local anaesthetic, sometimes with a steroid) can bring lasting relief
• Repeat injections are used if the pain returns
• Further nerve treatments or, rarely, surgery on the nerve are considered by pain specialists in resistant cases
Outlook
Abdominal wall pain is not dangerous. Once the correct diagnosis is made, many people improve substantially with simple treatments, and being reassured that there is no organ disease often helps in itself. Some people have recurring symptoms and need repeat treatment.
Questions to ask your doctor
• Is my pain coming from the belly wall rather than an organ?
• Which tests do I still need, if any?
• Would an injection help, and who performs it?
• Can physiotherapy help me?
