How long does a cortisone injection take to work for calcific tendinitis?

Short answer
A cortisone injection for calcific tendinitis may begin easing pain within several days, while the full effect can take longer and varies between people.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.
At a glance
- Early change
- Pain relief may start within several days.
- What it treats
- Inflammation around the affected shoulder tendon.
- What it does not do
- It does not directly dissolve the calcium deposit.
What the timing means
The medicine reduces inflammation around the irritated tendon and shoulder tissues. It does not remove the calcium deposit, so pain may improve without the underlying deposit changing immediately. A short-lived flare of soreness can occur after the injection. If the shoulder remains painful, your clinician may reassess movement, the deposit, and whether physiotherapy or another treatment is suitable.
What to do after the injection
Follow the activity and exercise instructions given for your shoulder. Gentle movement can help prevent stiffness, but avoid heavy lifting or repeated overhead work until advised. Note when pain, sleep, and range of movement change. Do not use the first few hours of numbness as a test of recovery, because local anaesthetic may temporarily mask symptoms.

When to seek care
Contact the treating service promptly if pain becomes severe or keeps worsening, the injection site becomes increasingly red or swollen, or you develop fever or feel unwell. Seek urgent help for breathing difficulty, facial swelling, or widespread hives. Arrange review if pain and shoulder restriction do not begin to settle as expected.
Questions for your doctor
Ask when to restart strengthening, how the calcium deposit will be monitored, and what your next option is if pain returns.
