Mastitis is inflammation of breast tissue that most commonly affects women who are breastfeeding, particularly within the first few weeks after giving birth. While mastitis can occur at other life stages, lactational mastitis is by far the most frequent presentation seen in clinical practice.

When breast tissue becomes inflamed, it can lead to significant pain, redness, heat, and systemic symptoms such as fever or flu-like feelings. In some cases, mastitis can become infective, requiring prompt medical treatment with antibiotics. If left untreated or poorly managed, mastitis can progress to a breast abscess, which is a collection of infected fluid and requires urgent medical intervention.

Mastitis is often linked to problems with milk flow, such as blocked milk ducts, engorgement, or ineffective milk removal. Early recognition and appropriate management are critical to reducing symptom severity, preventing complications, and allowing breastfeeding to continue comfortably.

Physiotherapy for mastitis, particularly with a trained Women’s Health Physiotherapist, can play an important role in early management. Physiotherapy focuses on improving milk drainage, reducing inflammation, relieving pain, and supporting ongoing breastfeeding. When started early, physiotherapy may help resolve symptoms more quickly and reduce the risk of infection or recurrence.

Key Facts

  • Lactational mastitis most commonly occurs within the first 6 weeks postpartum and affects a significant proportion of breastfeeding women. 🔗
  • If untreated, mastitis can progress to a breast abscess, which occurs in approximately 3% to 11% of women with mastitis. 🔗
  • Early conservative management that focuses on milk removal and inflammation control is associated with better outcomes and reduced need for invasive treatment.

Causes

Mastitis most commonly develops when milk flow is disrupted, leading to milk stasis and inflammation within the breast. This can happen when feeds are missed, breastfeeding is shortened too quickly, or milk is not being effectively removed from the breast.

Poor latch or attachment can prevent complete drainage of milk, increasing pressure within the ducts and contributing to blockage. Engorgement further increases this pressure and can compress milk ducts, making milk flow more difficult.

Skin damage around the nipple, such as cracks or sores, can allow bacteria to enter the breast tissue. When combined with milk stasis, this can lead to infective mastitis. External pressure from tight bras or prolonged pressure on one area of the breast can also restrict milk flow and contribute to inflammation.

Physiotherapy assessment focuses on identifying mechanical contributors such as blocked ducts, localised areas of engorgement, and postural factors that may be affecting milk drainage.

How Is It Diagnosed?

Mastitis is primarily diagnosed based on clinical symptoms and history. A healthcare professional will ask about breastfeeding patterns, recent changes in feeding frequency, breast pain, and systemic symptoms such as fever.

Physical examination often reveals localised breast tenderness, redness, warmth, and sometimes a palpable lump consistent with a blocked duct. In cases where symptoms are severe, recurrent, or not responding to initial management, further medical assessment is required to exclude abscess formation.

Physiotherapists trained in women’s health can identify blocked ducts, assess milk flow issues, and recognise when medical referral is required.

Physiotherapy Management

Physiotherapy for mastitis is most effective when commenced early, particularly before infection becomes established. Women’s Health Physiotherapists are trained to assess breastfeeding-related breast conditions and provide targeted, evidence-informed management.

The goals of physiotherapy are to reduce inflammation, promote effective milk drainage, relieve pain, and support continuation of breastfeeding where possible.

Exercise

Exercise is not the primary focus in mastitis management. However, physiotherapists may provide gentle mobility and postural advice to reduce sustained pressure on the breast and improve overall comfort during feeding and daily activities.

Activity Modification

Activity modification includes encouraging regular feeding or pumping to avoid milk stasis. Physiotherapists provide guidance on varying feeding positions to ensure all areas of the breast are adequately drained.

Manual Therapy

Manual therapy is a key component of physiotherapy for mastitis. Techniques may include gentle breast massage to assist milk flow, reduce duct blockage, and improve circulation. These techniques are specific and targeted, not aggressive, and are aimed at supporting natural drainage pathways.

Bracing & Taping

Taping techniques may be used to support the breast, reduce pain, and assist lymphatic and milk drainage. Taping is applied carefully and tailored to the individual’s breast size, symptoms, and feeding needs.

Shockwave

Therapeutic ultrasound may be used by physiotherapists to help open blocked milk ducts and reduce inflammation. This modality is applied specifically to areas of duct blockage and has been shown to assist symptom resolution when combined with other management strategies.

Heat & Ice

Heat and cold are used strategically. Warm compresses before feeding can help promote milk flow, while cold packs after feeding can assist with pain and inflammation management.

Education

Education is central to physiotherapy management. Physiotherapists provide advice on breastfeeding positions, latch optimisation, bra fit, hygiene practices, and early warning signs that require medical review.

Other

Physiotherapists work closely with GPs, lactation consultants, and maternal health nurses. If infection is suspected, prompt referral for antibiotic treatment is essential.

Prognosis & Return to Activity

With early and appropriate management, the prognosis for mastitis is very good. Most women experience symptom improvement within 24 to 48 hours of starting effective treatment. Delayed treatment increases the risk of abscess formation and prolonged recovery.

Physiotherapy can help reduce recurrence by addressing contributing mechanical and postural factors and improving breastfeeding efficiency.

When to See a Physio

  • If you notice breast pain, redness, or a lump that does not improve within 24 hours.
  • If you develop fever, chills, or flu-like symptoms while breastfeeding.
  • If you experience recurrent blocked ducts or mastitis episodes.
  • If breastfeeding pain is affecting your ability to continue feeding comfortably.

Frequently Asked Questions

Is mastitis an infection?
Mastitis can be inflammatory or infective. Early mastitis may not involve infection, but antibiotics are required if infection is suspected.

Should I keep breastfeeding with mastitis?
In most cases, continuing to breastfeed or express milk is recommended to help clear milk stasis, unless advised otherwise by a healthcare professional.

Can physiotherapy really help mastitis?
Yes. Women’s Health Physiotherapists can identify blocked ducts, use targeted techniques to promote drainage, and provide education to support recovery.

How quickly should mastitis improve?
With appropriate management, symptoms often improve within 24 to 48 hours. Lack of improvement should prompt medical review.

What happens if mastitis is left untreated?
Untreated mastitis can progress to infection or abscess formation, which requires urgent medical care.

Can mastitis come back?
Yes, recurrence is possible if underlying causes such as blocked ducts or poor milk drainage are not addressed. Physiotherapy can help reduce this risk.
