How to Use the Frozen Shoulder Recovery Calculator
Frozen shoulder (adhesive capsulitis) — where the shoulder stiffens and moving it in certain directions becomes difficult — is a chronic condition that can take anywhere from one to nearly three years to resolve on its own. It progresses through three stages (freezing, frozen, and thawing), so knowing which stage you're in is key to estimating how much longer recovery will take.
This calculator gives you the estimated remaining time for your current stage once you select where you are (freezing, frozen, or thawing) and whether you're doing physical therapy. The freezing stage, with worsening pain and shrinking motion, typically lasts 6 weeks to 9 months. The frozen stage, where pain eases but stiffness remains, usually runs 4-6 months. The thawing stage, where motion gradually returns, can take 6 months to 2 years. Some research suggests physical therapy and rehab exercises can shorten each of these stages somewhat.
Frozen shoulder often resolves on its own, but leaving it unaddressed can extend the total recovery time or leave lasting motion limitations. This calculator offers a general estimate based on typical progression and does not replace medical diagnosis. If pain is severe or motion is limited enough to interfere with daily life, please see an orthopedic specialist.
Frequently Asked Questions
The freezing stage brings increasing pain and decreasing motion, the frozen stage has less pain but persistent stiffness, and the thawing stage gradually restores range of motion.
The exact cause isn't fully known, but risk is higher in people with diabetes, those aged 40-60, and people who haven't used their shoulder for an extended period, such as after surgery.
Aggressive stretching during the painful early stage can actually make symptoms worse. It's safer to gradually increase range of motion under professional guidance, matched to your current stage.
