Mastitis physiotherapy may help ease breast pain, reduce swelling, and support comfortable feeding when you have a blocked duct or mastitis.

What are blocked milk ducts and mastitis?

Breastfeeding can sometimes be interrupted by breast tenderness, swelling, or a firm lump. Often, these symptoms sit on a continuum of breast inflammation during lactation. Early care matters because it can reduce symptoms and lower the chance of complications.

Blocked milk duct

A blocked duct (sometimes called a “plugged duct”) happens when milk flow becomes restricted in one area. As a result, you may notice a tender lump, localised swelling, and discomfort. Although the skin can look slightly red, many people don’t have a fever or feel unwell.

Mastitis

Mastitis means inflammation of the breast. It can start as local inflammation and, in some cases, progress to infection. Symptoms may include increasing redness, warmth, swelling, fever, chills, and fatigue. Therefore, early management can help prevent worsening symptoms and reduce the risk of an abscess.

Why mastitis and blocked ducts happen

Blocked ducts and mastitis usually relate to a mix of milk flow changes and local irritation. Common triggers include:

• Missed or delayed feeds, or long gaps between feeds
• Latch or positioning issues that reduce breast drainage
• Pressure from a tight bra, clothing, or a carrier strap
• Oversupply, sudden weaning, or changes to feeding routine
• Nipple damage, cracking, or skin irritation
• Stress, fatigue, and not drinking enough fluids

Early warning signs to take seriously

Get advice early if you notice any of the following:

• A firm or tender lump that persists beyond 24–48 hours
• Pain that increases during or after feeding
• Redness, swelling, heat, or a throbbing feeling
• Reduced milk flow from the affected area
• Flu-like symptoms or a fever above 38°C

Tip: Early care often settles symptoms faster and may reduce the chance of infection.

How physiotherapy may help

A women’s health physiotherapist may help you manage mastitis or blocked ducts alongside your GP or lactation consultant. At PhysioWorks, care usually targets symptom relief, better milk flow, and strategies to reduce flare-ups.

Physiotherapy management may include

• Gentle lymphatic-style techniques to help reduce swelling
• Feeding and expressing positioning advice to improve comfort
• Practical guidance for breast emptying without deep pressure
• Pain relief strategies and inflammation management
• Therapeutic ultrasound (when clinically appropriate)

Therapeutic ultrasound for blocked ducts and mastitis

Some clinical guidance recognises therapeutic ultrasound as a supportive option for breast inflammation during lactation when symptoms don’t settle with core feeding and comfort strategies. In practice, a physiotherapist may use ultrasound to support symptom management as part of a broader plan, not as a stand-alone treatment.

Ultrasound may assist by:

• Supporting local fluid movement
• Helping reduce local sensitivity and discomfort
• Assisting with circulation and tissue calming

Note: Research continues to develop. Your physiotherapist will tailor care to your presentation and coordinate medical review if needed.

Home self-management tips

Use these steps alongside physiotherapy and lactation support:

1. Feed or express regularly to maintain comfortable milk flow.
2. Apply gentle warmth before feeding if it helps let-down and comfort.
3. Use light, sweeping strokes toward the nipple (avoid deep lump massage).
4. After feeding, use a cool pack for 10–15 minutes to help settle swelling.
5. Avoid restrictive bras, tight tops, or anything that compresses the breast.
6. Rest where possible and keep fluids up.

When to see a doctor

See your GP promptly if you feel unwell or your symptoms escalate. In particular, organise medical review if:

• You have fever, chills, or body aches
• Redness spreads quickly or pain increases markedly
• You suspect an abscess
• Symptoms do not improve within 24–48 hours
• You have cracked, bleeding, or highly painful nipples

Also, your physiotherapist may recommend medical review sooner if your presentation suggests infection or you need prescription treatment.
