Frozen shoulder living in pregnancy

Overview

Frozen shoulder, also called adhesive capsulitis, is a condition where the shoulder joint becomes stiff and painful. During pregnancy, hormonal changes can sometimes lead to this problem. The shoulder capsule (the tissue that surrounds the joint) thickens and tightens, making it hard to move the arm.

Frozen shoulder is not extremely common during pregnancy, but it does happen in some pregnant women. It is more likely in the second half of pregnancy or in the months after giving birth.

It mostly affects pregnant women or new mothers, especially those in their 30s or 40s. Women with diabetes or thyroid problems may have a higher chance of developing frozen shoulder.

Symptoms

Common symptoms

• Dull, aching pain in the shoulder that can be worse at night
• Stiffness that makes it hard to lift your arm, reach behind you, or put on clothes
• Pain that slowly gets worse over weeks or months
• Limited range of motion, making everyday tasks like combing hair or fastening a bra difficult

Symptoms in children

• Frozen shoulder is very rare in children and is not usually linked to pregnancy. If a child has shoulder pain, other causes are more likely.

Symptoms in older adults

• Older adults may experience frozen shoulder for longer periods and with more stiffness. Recovery can take longer, but gentle exercise and physical therapy still help.

Causes

Main causes

• Inflammation and thickening of the shoulder joint capsule (the tissue that surrounds the joint)
• Hormonal changes during pregnancy, especially increased levels of the hormone relaxin, which can make ligaments looser and lead to instability
• Changes in activity or posture during pregnancy that put extra strain on the shoulder

Risk factors

• Pregnancy and the postpartum period
• Diabetes (including gestational diabetes)
• Thyroid disorders (overactive or underactive thyroid)
• Previous shoulder injury or surgery
• Immobilization of the shoulder for a long time (e.g., after an injury)

When to see a doctor

See a doctor urgently if:

• If you have sudden, severe shoulder pain after an injury, or if your arm is completely immobile, seek emergency care immediately.

Book a routine appointment if:

• If you notice persistent shoulder stiffness or pain that interferes with sleep or daily activities, make an appointment with your general practitioner or a physiotherapist.
• If you have diabetes or thyroid disease and develop shoulder pain, it is a good idea to check in with your healthcare provider.

Diagnosis

Your doctor or physiotherapist will ask about your symptoms and examine your shoulder. They will check how far you can move your arm in different directions. This is usually enough to diagnose frozen shoulder, especially during pregnancy when other causes are less common.

Tests that may be done

• X-rays may be done to rule out arthritis or a fracture.
• Ultrasound can look for problems in the tendons or fluid around the joint.
• MRI is rarely needed unless the diagnosis is unclear.

What to expect at your appointment

The exam should not be painful, though it may be uncomfortable if you are very stiff. Your healthcare provider will explain what they find and discuss a plan that is safe for you and your baby.

Treatment

Treatment focuses on reducing pain and improving mobility. Most cases of frozen shoulder get better on their own over several months, but therapy and gentle exercises can help you recover more quickly and with less discomfort.

Self-care at home

• Apply a warm pack or heating pad to the shoulder for 10–15 minutes before stretching.
• Do gentle pendulum swings (lean forward and let your arm hang down, then gently swing it in circles) for a few minutes each day.
• Avoid lifting heavy objects or overhead movements that cause sharp pain.
• Sleep with a small pillow under your affected arm to reduce pressure.

Medical treatments

Your doctor may suggest physiotherapy (hands-on stretching and exercises) to improve range of motion. In some cases, they might recommend a corticosteroid injection into the shoulder joint to reduce inflammation and pain. However, injections are used with caution during pregnancy and only when benefits outweigh risks. Pain relief options like paracetamol can be discussed with your healthcare provider, as they are generally considered safe in pregnancy. Do not take any medication without checking with your midwife or doctor.

When is surgery considered?

Surgery is rarely needed for frozen shoulder during pregnancy. It is considered only if the condition does not improve after many months of conservative treatment and severely impacts your daily life. Your surgeon will wait until after your baby is born if possible.

Living with this condition

Start your day with gentle shoulder stretches. Use your unaffected arm for tasks like lifting or reaching. When dressing, put the sore arm into sleeves first. Try to keep your shoulder moving a little each day, even if it is uncomfortable. Rest when you need to.

Lifestyle tips

• Avoid sudden, jerky movements with the affected arm.
• Use a sling only if your doctor advises it – otherwise, try to keep the arm active within pain limits.
• Ask for help with heavy household chores or carrying children.

Diet and exercise

Eating a balanced diet with plenty of fruits, vegetables, and protein supports tissue healing. Gentle exercise like walking and swimming (if comfortable) can keep muscles strong without stressing the shoulder. Your physiotherapist can give you a safe exercise plan.

Mental health and emotional wellbeing

Living with constant pain and limited mobility can be frustrating and isolating. It is normal to feel down or anxious, especially during pregnancy when you may also be dealing with other changes. Talk to your partner, family, or a friend about how you are feeling. Remember, this condition is temporary.

Prevention

There is no sure way to prevent frozen shoulder, especially during pregnancy. But keeping your shoulders and arms strong with regular, gentle exercise may reduce the risk. If you have diabetes, keeping your blood sugar under control may also help.

Complications

If left untreated

• Prolonged shoulder stiffness that may last more than a year
• Muscle weakness in the affected arm due to lack of use
• Long-term pain or discomfort in the shoulder

Long-term outlook

The outlook is very good. Most women with frozen shoulder during pregnancy recover fully within 6 to 12 months, even without treatment. With proper care and gentle exercises, you can speed up recovery and reduce pain. The condition does not harm your baby, and once it resolves, it rarely comes back in the same shoulder.
