Introduction
Every healing wound, whether from surgery, a muscle tear, a tendon rupture, or even a severe bruise, produces scar tissue. Scar tissue is the body's rapid repair mechanism: it fills the tissue defect quickly with type III collagen, restoring structural continuity. But this collagen is disorganised, laid down in a random matrix rather than the parallel, organised structure of the original tissue. Disorganised scar tissue can adhere to surrounding structures, restrict joint movement, alter sensation, generate pain, and transmit stress poorly compared to the original tissue. Understanding how scar tissue forms, what makes it problematic, and how massage, loading, and movement can remodel it is essential for anyone recovering from injury or surgery.
Whether you are dealing with a recent flare-up or something that has nagged you for years, understanding why your body hurts is the most important first step. This guide draws on the latest pain science, physiotherapy research, and practical coaching wisdom meticulously validated and referenced to give you peace of mind.
Understanding the Anatomy
The healing process produces scar tissue in three phases. The inflammatory phase (0 to 5 days): haemostasis, macrophage-mediated clean-up of damaged tissue, and the laying of provisional fibrin matrix. The proliferative phase (5 days to 3 weeks): fibroblasts produce type III collagen rapidly to fill the defect, the scar is formed here, but the collagen is disorganised and mechanically inferior. The remodelling phase (3 weeks to 2 years): type III collagen is gradually replaced by type I collagen; the collagen fibres begin to align with mechanical stress; and the scar matures. The key insight is that collagen aligns in the direction of mechanical stress, loading and movement during the remodelling phase produce a more functional, organised scar; immobility during this phase produces a dense, adherent, mechanically compromised scar.
Key structures involved: Fibroblasts (collagen-producing cells, drive scar formation), Type III collagen (early scar, disorganised, lower tensile strength), Type I collagen (mature scar, organised, high tensile strength), Myofibroblasts (in contractile scars, can create significant tissue contracture), Surrounding fascia and soft tissue (adherent scar tissue restricts these).
Why Does It Hurt? Root Causes
Modern pain science reminds us that pain is your nervous system's threat response, not simply a damage signal. That said, there are real, identifiable drivers.
1. Scar Adhesion
When scar tissue forms in a location where multiple tissue layers slide against each other, the layers of abdominal fascia after abdominal surgery, or the layers of the rotator cuff after shoulder surgery, the disorganised scar can adhere the layers together, preventing the normal sliding movement. Abdominal adhesions after surgery are a major cause of chronic pelvic and abdominal pain and bowel obstruction; shoulder capsule adhesions after injury or surgery produce the stiffness of frozen shoulder (adhesive capsulitis).
2. Hypertrophic and Keloid Scarring
Hypertrophic scars remain within the boundaries of the original wound but are raised and may become contracted. Keloid scars extend beyond the original wound boundaries and are driven by excessive fibroblast activity. Both are more common in darker skin types, after infection, and over certain body regions (anterior chest, shoulders, earlobes). Massage and silicone sheeting are evidence-supported interventions for hypertrophic scars.
3. Central Sensitisation from Scar Tissue
Scar tissue contains a dense network of nociceptors (pain receptors) during the early remodelling phase, making it hypersensitive to touch and movement. This sensitivity can persist well beyond the structural healing, driven by central sensitisation, the nervous system remaining in a heightened pain state despite adequate tissue healing. This is distinct from the scar causing structural restriction and requires different management.
How Massage Helps
Scar massage is one of the most evidence-supported applications of soft tissue therapy. The primary techniques include: cross-friction massage directly over the scar (working perpendicular to the scar line to break down adhesions and encourage collagen remodelling); skin mobilisation (lifting and moving the scar relative to the underlying tissue to address superficial adhesion); and myofascial release of the surrounding tissue (reducing the restriction that the scar has created in the adjacent fascial layers). Scar massage should begin when the wound is fully closed, typically 6 to 8 weeks post-surgery or injury. Starting before wound closure risks disrupting the healing process. Silicone gel or cream is often used as a medium during scar massage and has independent evidence for reducing scar thickness and redness.
Beyond specific mechanical effects, massage floods the nervous system with safe, rich sensory input, downregulating the threat response and creating conditions in which healing becomes easier.
Stretches to Try
Consistency matters far more than intensity. Gentle, daily stretching with calm breathing reduces perceived tightness and signals safety to the nervous system.
Gentle Scar Mobilisation
With clean hands and a moisturising cream or silicone gel, use the index and middle fingers to move the scar gently in all directions, up, down, sideways, and in circles. Perform for 5 to 10 minutes, 2 to 3 times daily. Benefit: Direct mobilisation of the scar promotes collagen remodelling and prevents adhesion to underlying structures.
Tissue Layer Mobilisation
Pinch and lift the skin adjacent to the scar. Move it in all directions relative to the underlying tissue. This addresses the superficial adhesions between skin and fascia. Benefit: Restores the normal sliding movement between skin and underlying fascia that scar adhesion disrupts.
Joint Range Restoration After Surgery
Through whatever range of motion is available, move the joint adjacent to the scar. Active movement (under your own muscle power) generates more appropriate collagen remodelling force than passive mobilisation. Benefit: Loading the scar tissue through joint movement during the remodelling phase produces more organised, functional scar tissue.
Strengthening Exercises
Loading tissues progressively tells your nervous system they are capable and resilient.
Progressive Loading Through the Scar
As healing permits, gradually increase the mechanical demands on the scarred tissue. The collagen fibres align with the direction of repeated mechanical stress, progressive loading produces a stronger, more organised, more functional scar. Benefit: Progressive loading is the evidence-based approach to scar remodelling, immobility produces the worst long-term outcomes.
Desensitisation Programme
For hypersensitive scars: begin with very light touch (a feather, then a finger, then firmer pressure) progressively over days to weeks. The goal is to normalise the nervous system's response to touch in the scarred area. Benefit: Central sensitisation of scar tissue requires a graded sensory exposure programme, the same principles as complex regional pain syndrome management.
Practical Self-Care
- Begin scar massage at 6 to 8 weeks post-surgery, not earlier (disrupts healing) and not later than 3 to 4 months (scar matures and becomes more resistant to remodelling).
- Silicone sheeting worn overnight significantly reduces scar thickness and redness, the evidence is among the strongest for any scar treatment.
- Keep scars out of UV light for 12 to 18 months, they hyperpigment easily and lose the pigment slowly.
- The discomfort of scar massage is normal and expected, pain signals tissue mobilisation, not damage.
- An abdominal scar that is causing restricted hip flexion, pelvic pain, or bowel symptoms 6 or more months post-surgery, scar massage and myofascial release can address adhesions months or years after surgery.
When to See a Professional
- Scar restricting joint range of motion not responding to massage after 3 months, manual therapy or specialist scar management input.
- Keloid scar, specialist referral for steroid injection, laser, or surgical revision.
- Scar tissue associated with nerve symptoms (burning, tingling, shooting pain), neuroma or nerve entrapment within the scar.
- Abdominal adhesion symptoms (bowel obstruction, severe pelvic pain), surgical assessment.
A qualified physiotherapist, sports therapist, or massage therapist can identify the specific drivers of your pain.
