Overview
A shoulder injection is a procedure where a healthcare provider uses a needle to deliver medicine directly into the shoulder joint or the soft tissues around it. The medicine is usually a combination of a steroid (a strong anti-inflammatory) and a local anaesthetic (painkiller). This injection can help reduce pain and swelling, making it easier to move your shoulder. It is often used for conditions like rotator cuff problems, bursitis, or arthritis, and can be part of a treatment plan before considering surgery.
Key facts
A shoulder injection can provide pain relief for several weeks to months.
It is a common procedure that is usually done in a doctor's office or clinic.
The injection may be guided by ultrasound to ensure the medicine goes to the right place.
Questions about this article
Multiple injections are generally not recommended over a short period due to potential side effects.
Shoulder injections are often used alongside physical therapy for best results.
Yes, shoulder injections are very common. Many people with shoulder pain due to inflammation or injury receive an injection as part of their treatment.
Shoulder injections are used for people of all ages who have shoulder pain from conditions like rotator cuff tears, frozen shoulder, shoulder arthritis, or bursitis. Athletes, older adults, and people with repetitive shoulder strain are most likely to need one.
Symptoms
Call emergency services immediately if you notice:
Sudden, severe shoulder pain after a fall or injury, especially if you cannot move your arm
Shoulder pain that comes with chest pain, shortness of breath, or cold sweat (could be a heart attack)
A shoulder that looks deformed or out of place (possible dislocation)
See a doctor urgently (same day) if you notice:
⚠Fever and redness or heat around the shoulder joint (possible infection)
⚠Severe pain that does not improve with rest or over-the-counter pain relief (as advised by a pharmacist)
⚠Numbness or tingling down the arm that is getting worse
Common symptoms
Pain in the shoulder that worsens with movement or at night
Stiffness or reduced range of motion in the shoulder
Swelling or tenderness around the shoulder joint
Weakness in the arm when lifting or reaching
Symptoms in children
In children, shoulder pain might be from injury or overuse, but injections are less common. Symptoms include crying when moving the arm, refusing to use the arm, or swelling around the shoulder.
Symptoms in older adults
Older adults often have shoulder pain from arthritis or rotator cuff tears. Symptoms include aching pain, stiffness in the morning, difficulty lifting objects, and trouble sleeping on the affected side.
Causes
Main causes
Inflammation of the shoulder joint or surrounding tissues (e.g., bursitis, tendonitis)
Rotator cuff tears – small or large tears in the muscles and tendons around the shoulder
Osteoarthritis – wear and tear of the cartilage in the shoulder joint
Frozen shoulder – thickening and tightening of the joint capsule
Risk factors
Repetitive overhead movements (e.g., in sports like tennis, swimming, or jobs like painting)
Age – older adults are more prone to arthritis and rotator cuff degeneration
Previous shoulder injury or dislocation
Diabetes – linked to a higher risk of frozen shoulder
Smoking – slows healing and increases risk of tendon problems
When to see a doctor
See a doctor urgently if:
If you have sudden, severe shoulder pain after an injury, or if your shoulder looks out of shape, go to an emergency department.
If you have shoulder pain with chest pain or trouble breathing, call your local emergency number immediately.
Book a routine appointment if:
If you have shoulder pain that lasts more than a week and is not improving with rest, ice, and over-the-counter pain relief (such as paracetamol or ibuprofen – ask your pharmacist), make an appointment with your GP or a physiotherapist.
If your shoulder is stiff and you cannot lift your arm above your head, see a healthcare provider for an assessment.
Many shoulder problems improve with simple measures like rest, gentle exercises, and time. A shoulder injection is not always needed. Your doctor will discuss if it is appropriate for you based on your specific condition and overall health.
Diagnosis
To decide if you need a shoulder injection, a doctor will first assess your shoulder. They will ask about your symptoms, how the pain started, and what makes it better or worse. They will also examine your shoulder, checking for tenderness, range of motion, and strength.
Tests that may be done
X-ray – to look for arthritis, fractures, or bone spurs
Ultrasound – to see soft tissues like tendons, bursa, or fluid
MRI scan – to get a detailed image of muscles, tendons, and ligaments, especially if a rotator cuff tear is suspected
Sometimes a doctor may inject a local anaesthetic to see if that temporarily relieves pain – this helps identify the source.
What to expect at your appointment
If you are having a shoulder injection, the doctor will clean the skin over your shoulder, then use a thin needle to inject the medicine. You may feel a brief sting. The procedure usually takes a few minutes. Afterward, your shoulder may feel sore for a day or two. Many people feel pain relief within a few days, though it can take up to a week.
Treatment
Treatment for shoulder pain often starts with rest, ice, and gentle exercises. If these do not help, a shoulder injection may be recommended to reduce inflammation and pain. The injection is not a cure but can provide relief for weeks to months, allowing you to do physical therapy more comfortably. For some conditions, surgery may be needed if the injection and other treatments do not work.
Self-care at home
Rest the shoulder for a day or two after the injection – avoid heavy lifting or overhead activities.
Apply ice packs for 15-20 minutes several times a day if there is swelling or soreness after the injection.
Gently move your shoulder as advised by your doctor or physiotherapist – do not keep it completely still for long.
Avoid heat for the first 24 hours after the injection, as it may increase swelling.
Medical treatments
A shoulder injection usually contains a steroid (to reduce inflammation) and a local anaesthetic (to numb pain). The type and dose of steroid will be chosen by your healthcare provider. You may be advised to avoid over-the-counter painkillers like ibuprofen for a few days before the injection, as they can affect how the steroid works. In some cases, a doctor may recommend a second injection, but this is usually spaced months apart. Physical therapy is often recommended after the injection to strengthen shoulder muscles and improve movement.
When is surgery considered?
Surgery for shoulder problems is considered when an injection and other treatments do not provide lasting relief, or if there is a large rotator cuff tear, a dislocated shoulder that does not heal, or advanced arthritis. Your surgeon will discuss the best option for you, which may include arthroscopic repair (keyhole surgery) or shoulder replacement.
Living with this condition
After a shoulder injection, most people can return to light daily activities within a day or two. Avoid heavy lifting or strenuous sports for at least a week. Follow your doctor's advice on when to start physical therapy. If you have persistent pain, pace yourself and use the arm gently.
Lifestyle tips
Avoid sudden, jerky movements with the affected arm.
Sleep with a pillow under your arm to support your shoulder if it is uncomfortable.
If your job involves repetitive shoulder movements, talk to your employer about modifications or ergonomic adjustments.
Stay active, but choose low-impact activities like walking or swimming (when cleared by your doctor).
Diet and exercise
A balanced diet rich in calcium (e.g., milk, yogurt) and vitamin D (e.g., fatty fish, fortified foods) supports bone and joint health. Omega-3 fatty acids (e.g., from nuts and seeds) may help reduce inflammation. Gentle stretching and strengthening exercises, as prescribed by a physiotherapist, can improve shoulder function. Avoid exercises that cause sharp pain.
Mental health and emotional wellbeing
Ongoing shoulder pain can be frustrating and affect your mood, sleep, and ability to do things you enjoy. It is normal to feel down or anxious. Talk to your healthcare provider about how you are feeling – they can help. If you feel overwhelmed, consider reaching out to a mental health professional or a support group.
Prevention
Not all shoulder problems can be prevented, but you can reduce your risk by staying active, using proper technique during sports and work, and avoiding overuse. Strengthening the muscles around your shoulder with regular exercises can help protect the joint. If you feel shoulder pain, rest and ice early to avoid worsening the injury.
Vaccines
There is no vaccine for shoulder problems, but getting the flu and pneumonia vaccines (if recommended for your age) can prevent infections that might affect joints.
Screening programmes
There is no routine screening for shoulder conditions. See a doctor if you have persistent shoulder pain or stiffness.
Complications
If left untreated
Chronic pain and stiffness that limits daily activities
Muscle weakness and loss of shoulder function
Progression of joint damage (e.g., arthritis) over time
Frozen shoulder that becomes difficult to treat
In rare cases, infection in the joint if an untreated injury gets infected
Long-term outlook
The outlook for shoulder problems is good for most people. With proper treatment – including rest, physical therapy, and sometimes an injection – many regain full or near-full function. Even if you need surgery, recovery is often successful. Following your healthcare provider's advice and being patient with your recovery can help you return to your usual activities.
