Shoulder condition
Calcific tendinitis is a calcium deposit that forms inside a rotator cuff tendon — and it is responsible for some of the sharpest, most alarming shoulder pain there is. It can sit silently for a time, then flare into pain so severe that people fear something has ruptured. The surprising part is that this violent phase is often the deposit dissolving — the body reabsorbing it — which is why calcific tendinitis frequently clears on its own in the end. The problem is the “in the end” can mean months of pain. This page explains why it hurts so suddenly, what settles a flare, and how a stubborn deposit can be cleared rather than simply endured.
Tap any that apply to you — this is guidance, not a diagnosis, but it helps tell calcific tendinitis from other shoulder pain.
The pattern fits calcific tendinitis — but that last one needs ruling out first. Fever, a hot swollen joint or feeling unwell can point to infection rather than a calcium flare, and that needs prompt assessment. Otherwise, sudden severe shoulder pain with a deposit on X-ray is the classic picture, and there is a lot that can settle it faster than waiting. Get it assessed rather than enduring the flare unaided.
If your shoulder pain is more of a gradual ache than a sudden severe flare, it may be something other than a calcium deposit. Impingement, a cuff problem or frozen shoulder can feel similar and are managed differently. An assessment — with an X-ray, which shows a deposit clearly — sorts out which it is and sets the right plan.
Calcific tendinitis has a life cycle, and understanding it explains the pain:
An acute calcific flare is genuinely painful, and the aim is to settle the pain while keeping the shoulder gently mobile, not to force it or freeze it. In the worst days, supporting the arm and gentle movement within comfort helps; measures to calm the inflammation make the flare more bearable while the body does its work. Two things to avoid: pushing through the sharp pain with heavy or overhead use tends to worsen an already inflamed tendon, and at the other extreme, immobilising the shoulder completely for a prolonged period risks it stiffening into a frozen shoulder once the flare passes. If the pain is severe and not settling, that is worth getting help with rather than enduring — there are effective ways to shorten the flare. And if you feel feverish or unwell with a hot, swollen shoulder, get it assessed promptly, because that points away from a simple calcium flare.
The right step depends on the phase — tap the one that fits:
The priority now is settling the pain. An acute flare is often the deposit reabsorbing — intensely painful, but a phase. Calming the inflammation and keeping the shoulder gently moving makes it bearable, and there are effective ways to shorten a severe flare rather than waiting it out. Getting help early is worth it when the pain is this sharp.
A deposit that will not settle can be helped to clear. Where a deposit lingers and keeps the shoulder sore, shockwave therapy can break it down, and needle barbotage can wash it out directly under imaging. These target the deposit itself rather than only masking the pain, and physiotherapy restores movement alongside.
Recurring deposits deserve a fuller look. A shoulder that keeps forming stubborn deposits is worth assessing properly — both to plan the most durable way to clear them and to check for associated conditions such as diabetes or thyroid problems that can play a part.
Calcific tendinitis treatment is a ladder, and most people need only the earlier rungs:
Tap each card to reveal the truth:
Calcium deposits form inside the rotator cuff tendons — exactly why is not fully understood, though it is not caused by too much calcium in the diet. For a while a deposit may sit there quietly. The severe, sudden pain usually comes when the body starts to reabsorb the deposit: as it breaks down it can inflame sharply and raise pressure inside the tendon, producing some of the most intense shoulder pain there is. Counterintuitively, that violent phase is often a sign the deposit is on its way out — the body is dissolving it.
Very often, yes. Many deposits are eventually reabsorbed by the body and the shoulder settles, sometimes over weeks to months, occasionally longer. The catch is that the reabsorption phase can be extremely painful while it lasts, and there is no reliable way to predict how long a given deposit will take. So while calcific tendinitis is frequently self-limiting, treatment is not about forcing a cure that would not otherwise come — it is about controlling the pain, and, for stubborn deposits, helping them clear sooner rather than waiting months in discomfort.
It depends on the phase and the severity. An acute, intensely painful flare is managed first by settling the pain and keeping the shoulder gently moving. For deposits that will not settle or keep flaring, shockwave therapy can help break them down, and needle barbotage — using a fine needle under imaging to break up and wash out the deposit — can remove it directly. Guided physiotherapy restores movement and strength as the shoulder calms. Keyhole surgery to remove a deposit is reserved for the few that resist everything else.
No, though both involve the rotator cuff and can be confused. Calcific tendinitis is a calcium deposit within a tendon that is otherwise intact; a rotator cuff tear is the tendon itself torn. They feel different too: calcific tendinitis classically causes sudden, severe pain out of proportion to any injury, often without weakness, while a cuff tear more typically causes weakness lifting or rotating the arm, often after a specific strain. An X-ray shows the calcium deposit clearly, which is why imaging quickly settles the question.
It can. Even after a deposit clears — on its own or with treatment — a new one can form later, in the same shoulder or the other one, and some people are simply more prone to them. That said, many people have a single episode that resolves and never troubles them again. If a deposit does recur, the same ladder of treatment applies, and a shoulder that keeps forming stubborn deposits is worth a fuller assessment to plan the most durable approach rather than repeatedly managing flares.
