When are steroid injections used for bursitis in the shoulder or hip? 

Steroid injections, also known as corticosteroid injections, are a specialized treatment used to reduce severe inflammation in the bursae of the shoulder or hip. In the United Kingdom, they are typically considered a second line treatment when conservative measures, such as rest, ice, and oral anti-inflammatory medications, have failed to provide adequate relief. The primary goal of a steroid injection is to deliver a potent dose of anti-inflammatory medication directly to the site of the swollen bursa, helping to break the cycle of chronic pain and allow a patient to engage more effectively in physiotherapy.

Clinical criteria for a steroid injection 

A GP or musculoskeletal specialist will usually only recommend a steroid injection if your bursitis is significantly impacting your daily life or sleep. For shoulder bursitis, this often means you are unable to lift your arm to perform basic tasks or have persistent night pain. For hip bursitis, also known as greater trochanteric pain syndrome, an injection is considered if the pain prevents you from walking comfortably or lying on your side. According to NHS information on steroid injections, they are most effective when the diagnosis is clear and the pain is localized to a specific bursa sac. 

How steroids settle deep inflammation 

Corticosteroids are synthetic versions of hormones naturally produced by the adrenal glands. When injected into a bursa, they work by suppressing the immune system’s inflammatory response and reducing the production of excess fluid within the sac. Unlike oral tablets, which must travel through the entire bloodstream, an injection provides a high concentration of the drug exactly where it is needed. Many patients experience a significant reduction in pain and swelling within a few days of the procedure, which can last for several weeks or even months, providing a vital window for joint recovery. 

The importance of ultrasound guidance 

In many UK clinics, steroid injections for the hip and shoulder are performed under ultrasound guidance. Because the bursae are located deep beneath layers of muscle and fat, using a real time scan ensures that the needle is placed accurately within the thin bursa sac rather than in the surrounding tendons or muscles. This increases the effectiveness of the treatment and reduces the risk of accidental damage to nearby tissues. NICE clinical standards for musculoskeletal health suggest that guided injections are particularly beneficial for hip bursitis, where the target area can be more difficult to pinpoint through physical touch alone. 

What to expect during the procedure 

The injection process is relatively quick and is usually performed in a GP surgery or a hospital outpatient department. The area will be cleaned, and the clinician may use a local anaesthetic to numb the skin before the steroid is administered. You may feel a sensation of pressure or a slight sting as the fluid enters the bursa. After the injection, it is common for the joint to feel a little more sore for a day or two; this is known as a steroid flare. Most patients are advised to rest the joint for forty eight hours following the procedure to allow the medication to settle into the tissues effectively. 

Potential risks and limitations 

While steroid injections are generally safe, they are not without risks, and there are strict limits on how often they can be used. Potential side effects include thinning of the skin at the injection site, a temporary change in skin color, or a small risk of infection. If you have diabetes, a steroid injection can cause a temporary rise in your blood sugar levels. Most importantly, repeated injections in the same area can eventually weaken the nearby tendons and ligaments. For this reason, NHS clinicians usually limit patients to no more than two or three injections in the same joint within a twelve month period. 

Combining injections with physiotherapy 

A steroid injection is rarely seen as a permanent cure on its own. Instead, it is a tool used to facilitate long term healing through rehabilitation. Once the intense pain has been reduced by the steroid, it is essential to work with a physiotherapist to address the underlying mechanical issues that caused the bursitis. This involves strengthening the muscles around the shoulder blade or the gluteal muscles in the hip to take the pressure off the bursa. Without this follow up work, the inflammation is likely to return once the effects of the steroid have worn off. 

Conclusion 

Steroid injections are used for shoulder and hip bursitis when persistent pain and inflammation have not responded to standard rest and medication. They provide targeted, potent relief that can help restore mobility and enable a return to physiotherapy. While they are highly effective for managing severe flares, they must be used judiciously to avoid tissue damage and are most successful when combined with a structured exercise program. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
