Have you ever reached back for a seatbelt and felt your shoulder stop cold? For a lot of people, that stiff, sore shoulder is more than a pulled muscle. It may be a problem called frozen shoulder. The good news is that it almost always gets better with the right care.
Frozen shoulder, also called adhesive capsulitis, happens when the tissue around your shoulder joint gets thick and tight. Think of that tissue like a stretchy sleeve wrapped around the joint. When it swells and stiffens, your arm gets stuck. Even small moves can hurt.
By the numbers: Frozen shoulder affects about 1 in 100 adults. It shows up most between ages 40 and 60, and more often in women than men.
What causes frozen shoulder?
Doctors are still not sure why it starts. It often shows up after an arm has been still for a while, like after surgery or an injury. Some health problems raise your risk too. People with diabetes or thyroid trouble get it more often.
Not every stiff shoulder is frozen shoulder. Sometimes the real trouble is shoulder impingement, swimmer’s shoulder, or pain between the shoulder blades. These feel different and are treated in different ways, so it helps to get a clear diagnosis first.
What are the stages of frozen shoulder?
Frozen shoulder moves through three stages. In the freezing stage, pain grows and the joint starts to lock up. This part can last a few months. In the frozen stage, the pain may ease, but the stiffness stays, and simple tasks like combing your hair feel hard. In the thawing stage, motion slowly comes back.
Catching it early matters. One 2024 study found that people treated before the shoulder fully locked up got their range of motion back faster [3].
How long does frozen shoulder last?
This is the hard part. Frozen shoulder is slow. It can take one to three years to fully clear. But you do not have to just wait it out. The right care can lower the pain and help you move sooner.
What actually helps?
Gentle movement is the main treatment. Stretching and range-of-motion work keep the joint from getting worse. One 2023 trial found that neuromuscular exercises, which train the muscles to work together, lowered pain and improved motion more than plain strength work over eight weeks [2].
Hands-on care can help too. Manual therapy, where a trained provider carefully moves and stretches the joint, is often paired with exercise. A 2023 research review found this combo is common in practice, though experts are still studying the best amount of treatment [1]. A 2025 trial found that guided stretching methods eased pain and improved daily function in just six weeks [5].
Some people also try heat, laser, or steroid shots. One 2023 review found that laser therapy lowered pain, but it did not beat regular therapy for restoring motion [4]. Chiropractic care, physical therapy, and a simple home exercise plan are all options worth talking over with a provider.
Simple moves you can try
Check with a provider first, then try these gentle moves. Let your arm hang and swing it in small circles, like a slow pendulum. Walk your fingers up a wall, going a little higher each day. Use your good arm to pull the sore arm softly across your chest. Move slowly, and never push into sharp pain.
How to protect your shoulder going forward
Keep the shoulder moving after any injury or surgery, and do not let it sit still for weeks. If you feel stiffness starting, act early. Staying active and keeping conditions like diabetes under control can lower your risk.
The bottom line
Frozen shoulder is stubborn, but it is not forever. Most people get their motion back with patience, gentle exercise, and good guidance. The key is to start care early and keep the joint moving in a safe way.
If your shoulder is stiff and sore and will not loosen up, do not ignore it. A provider can check what is going on and build a plan that fits your body and your goals.
