A steroid (cortisone) injection in the shoulder is commonly used to reduce pain and inflammation caused by conditions such as frozen shoulder (adhesive capsulitis), bursitis, or rotator cuff–related pain. While the injection itself is quick, what you do afterwards plays a key role in how effective the treatment is.
At Alton Pain Clinic, we provide ultrasound-guided shoulder injections, and clear aftercare advice to help maximise pain relief and recovery.
Avoid Overusing the Shoulder for 24–48 Hours
After a shoulder steroid injection, you should avoid:
- Heavy lifting
- Pushing or pulling
- Repetitive or overhead arm movements
- Gym workouts or sports
Although pain may improve quickly, the shoulder joint needs time to settle. Overusing it too soon can irritate the joint capsule and reduce the effectiveness of the injection.
Don’t Return to Sport or Strenuous Exercise Immediately
Even if your shoulder feels better, don’t rush back into high-impact or strenuous activities. Returning to sport too early may worsen inflammation or trigger a pain flare.
A clinician at Alton Pain Clinic in Alton will advise when it is safe to gradually increase activity, depending on your condition and treatment plan.
Don’t Ignore a Post-Injection Pain Flare
It’s common to experience:
- Mild soreness
- Temporary increase in pain
- Stiffness for 24–72 hours
However, don’t ignore red flags, such as:
- Increasing redness or swelling
- Severe pain that doesn’t settle
- Fever or feeling unwell
These symptoms should be reported promptly, as they may require review.
Don’t Apply Heat in the First 24 Hours
Avoid heat packs or hot showers directly over the injection site on the first day. Heat can increase inflammation.
Instead:
- Use a cold pack if needed
- Keep the area clean and dry
Heat may be introduced later if advised by your clinician.
Don’t Completely Stop Moving Your Shoulder
While rest is important, complete immobilisation can increase stiffness, particularly in frozen shoulder.
After the initial rest period:
- Resume light daily activities
- Gently move your shoulder within comfort
This balance helps maintain range of motion and supports long-term improvement.

Key Takeaway
At Alton Pain Clinic, our clinicians use ultrasound guidance for shoulder injections where appropriate.
Ultrasound allows the clinician to visualise relevant structures and guide the needle towards the intended treatment area.
The suitability of an injection is confirmed following a clinical assessment.

Hyaluronic Acid Injections
Hyaluronic acid (HA) injections can help improve joint lubrication by replenishing the natural hyaluronic acid found within the joint. This may reduce friction between joint surfaces, support smoother movement and help improve comfort during everyday activities.

PRP Injections
Platelet-rich plasma (PRP) injections use a concentrated preparation of your own platelets to support the body’s natural healing processes within the affected joint. They may help support tissue repair, reduce discomfort and promote improved joint function and mobility.
