Your Rotator Cuff Isn’t Just Tight: Understanding Calcific Tendinitis and How to Treat It

You’ve tried stretching, resting, and maybe even taking ibuprofen, but your shoulder still hurts.

If this sounds familiar, your pain might not be from muscle tightness. It could be calcific tendinitis, which requires a different kind of treatment.

What Is Calcific Tendinitis?

Calcific tendinitis develops when calcium deposits form inside the tendons of your rotator cuff. These deposits put pressure on the tendon and cause irritation, which leads to pain.

Most often, the supraspinatus tendon, one of the four tendons in your rotator cuff, is affected. The calcium deposits can be as small as a few millimetres or as large as a centimetre. Pain usually starts when the deposits reach 1 cm or more.

Calcific tendinitis usually affects people between the ages of 40 and 60, and women have a slightly higher risk than men. It isn’t linked to any specific activity, so it can happen to anyone.

What Does It Actually Feel Like?

This is the stage when calcific tendinitis is often mistaken for simple muscle tightness.

Common symptoms include sharp or intense pain on the side of your shoulder, pain that can spread toward your elbow, difficulty lifting your arm overhead, pain that wakes you up at night, and sudden flare-ups that seem to come on without warning.

That last symptom is important. The pain often comes and goes. Some days are manageable, but then it can suddenly become unbearable, sometimes so severe that people go to the emergency room. This usually occurs during the resorptive stage, when calcium begins to break down, and pressure within the tendon rises rapidly.

The Four Stages You Should Know

Calcific tendinitis goes through several stages, and the stage you are in will affect your treatment options.

Pre-precalcific: This is when changes begin at the cellular level. There’s no pain yet, so you won’t notice anything.

Calcific: Deposits form. This is a relatively quiet phase for now.

Resorptive: This is the painful stage. The deposits soften, pressure increases, and inflammation flares up. Most people seek help during this phase.

Post-calcific: The deposits break down and are replaced by healthier tissue. Pain decreases, and your movement gets better.

Not everyone experiences these stages in the same order, and each stage can last for several weeks or even months.

How Is It Diagnosed?

A physiotherapist will check your range of motion, strength, and symptoms. However, a physical exam alone can’t confirm whether calcium is present in the tendon.

Diagnostic ultrasound is the best way to detect calcium deposits. It is more sensitive than MRI or X-ray and can also show which stage you are in. This is important because the timing of treatment matters.

How Physiotherapy Treats It

Physiotherapy is often the first and one of the most effective treatments for calcific tendinitis.

Your physiotherapist will start by helping to reduce pain and inflammation, restore your shoulder’s range of motion, correct your posture and shoulder blade alignment, and gradually rebuild rotator cuff strength. Since poor posture can put extra pressure on the rotator cuff, fixing it is an important part of recovery.

If your pain is severe, a steroid injection into the inflamed bursa can give short-term relief. This period can help you get more benefit from your physiotherapy sessions.

Where Shockwave Therapy Comes In

After the most painful phase has passed, shockwave therapy Milton can be a very effective next step.

Shockwave therapy in Milton targets the calcium deposits directly. It uses focused sound waves on the affected tendon to trigger a healing response. Research shows this treatment can break up calcium deposits, help your body reabsorb them, and reduce pain by calming the nearby nerves.

The course is three to six sessions, paired with physiotherapy for the best results.

Timing matters. Shockwave therapy Milton isn’t recommended during the most painful stage. Your physiotherapist will tell you when it’s the right time to start.

If rest and stretching haven’t helped, shockwave therapy in Milton might be the step that finally helps you make progress.

Other Options If Needed

Lavage (barbotage): This procedure uses a needle to break and flush out the calcium deposits. Studies suggest it can be as helpful as surgery for some people.

Surgery: This option is used only when all other treatments haven’t worked, which occurs in about 10% of cases. Recovery usually takes about six weeks.

When Should You Get Help?

Don’t wait until the pain becomes unbearable.

If your shoulder hurts when you move it overhead, wakes you up at night, or hasn’t improved after weeks of rest, get it checked by a professional. Early diagnosis means early treatment and faster recovery.

Calcific tendinitis can be successfully treated, but it requires an appropriate treatment plan, not just more rest.
