Frozen Shoulder: Why It Happens, the Three Phases, and How Long It Lasts

If you have started struggling to reach the back seat of the car, to fasten a bra strap, or to lift a bag onto a two-wheeler, and your shoulder now aches even at night, you are not imagining it. Many people who walk into the clinic in Viman Nagar with these exact complaints are surprised to learn there is a name for it: frozen shoulder, or adhesive capsulitis.

I want to be honest with you from the start. Frozen shoulder is one of the slower conditions we treat. It settles over many months, not days. The good news is that it usually does improve, and understanding what is happening inside the joint makes the wait far less frightening.

What frozen shoulder actually is

Your shoulder is wrapped in a soft envelope called the capsule. In frozen shoulder, this capsule becomes inflamed, thickens, and tightens like a shrunk shirt around the joint. The result is a shoulder that is both painful and genuinely stiff, so the movement is limited even when someone else tries to lift your arm for you. That last point matters. A muscle knot loosens when you relax. A frozen shoulder does not, because the restriction is in the capsule itself.

Because the loss of movement is mechanical and not just pain avoidance, you cannot simply push through it or stretch it out in a week. This is why the condition tests everyone's patience, including the patient and the doctor.

Why it happens, and who tends to get it

In many cases we never find a single clear cause, and that is normal. But there are well known patterns. It commonly appears in people in their 40s, 50s, and 60s, and a little more often in women. A strong association we watch closely is with diabetes. If your blood sugar has been high, you are more prone to frozen shoulder, it can affect both shoulders over time, and it often takes longer to settle. That is not meant to alarm you, only to explain why we ask about diabetes and why keeping sugar controlled genuinely helps recovery.

It also tends to follow a spell of the shoulder being kept still. A fracture in a plaster, a period after surgery elsewhere, a painful injury, or long rest can all lead the capsule to tighten. Thyroid problems and some heart conditions are linked as well.

• Age in the 40s to 60s, and slightly more common in women
• Diabetes, which raises the risk and can slow recovery
• A recent injury, fracture, or a shoulder kept still for a long time
• Thyroid disorders and certain other long standing conditions

The three phases, and how long each lasts

Frozen shoulder usually moves through three phases. The timeline below is a general guide, not a fixed rule. Everyone is different, and people with diabetes often sit at the longer end of each stage.

Read that table and you will see why we talk in terms of months. Taken end to end, the whole cycle commonly runs well over a year. It can feel slow, especially in the frozen phase when nothing seems to change. But the thawing phase does tend to come, and gentle, consistent effort helps you get more of your movement back.

How it is usually managed

The aim of treatment is to control pain and to keep the shoulder moving as much as it comfortably allows, so it does not stiffen further. Guided physiotherapy and a set of home exercises are the backbone of care. Doing a little, often, through the day usually helps more than one hard session that leaves you sore. A physiotherapist teaches you how to move safely without forcing the joint.

For pain, especially the night pain that disturbs sleep, your doctor may suggest options during your visit. I will not name specific medicines here, because the right choice depends on you, your other health conditions, and your diabetes if you have it. That decision belongs in the consultation room. In selected cases, when pain is severe or progress has stalled, a doctor may discuss further options with you, including a referral to the right facility if any treatment beyond what an outpatient clinic offers is needed. Please do not start or stop any medicine on your own.

There is no instant fix and no button that unfreezes a shoulder overnight. What I can tell you honestly is that with the correct diagnosis, steady physiotherapy, good sugar control, and a bit of patience, most people improve meaningfully over time.

When to see a doctor

It is worth getting your shoulder checked rather than assuming any stiff shoulder is a frozen shoulder. Some other problems, such as a tendon tear or arthritis, can feel similar and need different care. Come in if any of the following apply to you.

• Shoulder pain and stiffness that has lasted more than a couple of weeks and is not easing
• Night pain that is disturbing your sleep
• Difficulty with daily tasks such as dressing, combing hair, or reaching behind your back
• The shoulder became stiff after an injury, a fall, or a long period in a plaster
• You have diabetes and are noticing new shoulder stiffness

One safety note. Frozen shoulder builds up gradually. If instead you have sudden severe chest pain, or pain spreading into the arm or jaw with sweating or breathlessness, do not wait to think about your shoulder. Call 108 or go to the nearest emergency hospital at once, because those can be signs of a heart problem.
