Frozen Shoulder: Why It Happens and How to Get Moving Again

Frozen shoulder is one of the most frustrating conditions a person can deal with, partly because it comes on gradually, lasts a long time, and progressively steals your ability to move your arm. The medical name is adhesive capsulitis, and it involves the shoulder joint capsule thickening, tightening, and becoming inflamed until the joint genuinely freezes in place. At Axiom Chiropractic in Southpark, we help frozen shoulder patients reduce pain and restore motion by addressing both the shoulder itself and the cervical spine factors that often contribute to it.

What Frozen Shoulder Actually Is

The shoulder is surrounded by a capsule of connective tissue that normally allows a wide, free range of motion. In frozen shoulder, this capsule becomes inflamed, thickens, and develops adhesions, bands of stiff scar-like tissue that bind the capsule down and restrict movement. As the condition progresses, the capsule tightens further and the shoulder loses more and more range of motion.

What makes frozen shoulder distinct from other shoulder problems is this progressive stiffening. It’s not a torn muscle or a single injury. It’s a gradual, often spontaneous tightening of the entire joint capsule that follows a recognizable pattern over many months.

The Three Stages

Frozen shoulder typically moves through three phases, and understanding where you are in the process matters for treatment.

The freezing stage comes first, lasting anywhere from six weeks to nine months. Pain gradually increases and range of motion progressively decreases. This is often the most painful phase, with discomfort that can disrupt sleep and make everyday movements difficult.

The frozen stage follows, lasting roughly four to twelve months. The pain may actually ease somewhat during this phase, but stiffness is at its worst. The shoulder is genuinely stuck, and simple tasks like reaching overhead, fastening a seatbelt, or putting on a jacket become very difficult.

The thawing stage is the recovery phase, lasting six months to two years. Range of motion gradually returns as the capsule loosens. Left entirely alone, many frozen shoulders do eventually thaw, but the full cycle can take two to three years, which is a very long time to live with a painful, restricted shoulder.

Who Gets Frozen Shoulder and Why

Frozen shoulder most commonly affects people between 40 and 60 and is more frequent in women. Several factors raise the risk. Diabetes is one of the strongest, with diabetics significantly more likely to develop it. Thyroid disorders are also associated with higher risk. A period of shoulder immobilization, after an injury, surgery, or even just protective guarding from pain, can trigger it, because the lack of movement contributes to the capsule tightening.

This immobilization link is important. Sometimes a minor shoulder problem causes a person to stop using the arm normally, and that reduced movement sets off the frozen shoulder cascade. The original problem may have been small, but the protective disuse triggered something much larger.

The Cervical Spine Connection

Here’s a factor that’s frequently overlooked in frozen shoulder. The muscles that move and stabilize the shoulder receive their nerve supply from the cervical spine, primarily the C5 and C6 nerve roots. When these cervical levels are misaligned and the nerve supply to the shoulder muscles is compromised, it affects how those muscles function.

Impaired nerve supply can lead to muscle weakness, altered movement patterns, and reduced normal motion at the shoulder, which is exactly the kind of reduced movement that can contribute to the capsule tightening that defines frozen shoulder. A cervical problem can also create shoulder pain that leads a person to guard and underuse the arm, setting up the immobilization that triggers the freezing process.

This doesn’t mean every frozen shoulder is caused by the neck. But the cervical spine is a genuine contributing factor that’s rarely assessed in frozen shoulder cases, and addressing it can support recovery and help prevent the kind of altered mechanics that perpetuate the problem.

How We Approach Frozen Shoulder at Axiom

When a Southpark patient comes in with frozen shoulder, we assess both the shoulder and the cervical spine, since both are usually relevant.

Full-spine, weight-bearing X-rays show the position of the lower cervical vertebrae that supply the shoulder muscles. Nervoscope instrumentation identifies nerve irritation at these levels. We assess the shoulder joint itself for range of motion, the stage of the condition, and the specific movement restrictions present, and we evaluate the cervical spine and surrounding musculature.

Treatment addresses both areas. Specific Gonstead chiropractic adjustments correct cervical misalignments affecting the nerve supply to the shoulder, supporting better muscle function and movement. We also work to restore motion to the shoulder joint and surrounding structures through appropriate, gentle mobilization suited to the stage of the condition.

The stage matters here. In the painful freezing stage, treatment is gentler and focused on managing pain and maintaining whatever motion is available. In the frozen and thawing stages, more can be done to actively restore range of motion. We adapt the approach to where you are in the process. Our extremity pain page and neck pain page cover the related mechanisms in more detail.

Red Light Therapy for the Inflammation Component

Because frozen shoulder involves significant inflammation of the joint capsule, red light therapy can be a valuable complement to chiropractic care. Photobiomodulation reduces inflammatory markers in the tissue and supports the cellular repair processes involved in remodeling the tightened, scarred capsule.

Combining shoulder and cervical correction with red light therapy addresses the structural, neurological, and inflammatory dimensions of frozen shoulder at the same time, which can help shorten the prolonged course this condition typically takes when left to resolve on its own. You can read more about how this works on our red light therapy page.

What You Can Do at Home

Gentle, consistent movement within your pain-free range is one of the most important things you can do for frozen shoulder. Complete immobilization makes it worse, so keeping the shoulder moving as much as comfort allows, without forcing through sharp pain, helps maintain whatever motion you have and supports the eventual thawing.

Pendulum exercises, where you let the arm hang and gently swing it in small circles, are a common starting point because they move the joint without much muscular effort. Applying heat before gentle movement can help the tissue loosen. We’ll guide you on appropriate home movements based on your stage and presentation, since the right exercises change as the condition progresses.

Frequently Asked Questions

Won’t my frozen shoulder eventually go away on its own?

Many do, but the natural course can take two to three years, and that’s a long time to live with pain and significant restriction. Active treatment aims to reduce pain, maintain and restore motion, and potentially shorten that timeline rather than simply waiting out the full cycle. Addressing contributing factors like cervical involvement also helps prevent prolonged altered mechanics.

I have diabetes and frozen shoulder. Does that change anything?

Diabetes is associated with more stubborn and sometimes more prolonged frozen shoulder, so consistent care and patience matter even more. Our functional medicine side can also be relevant here, since blood sugar management and inflammation are connected to how the tissue heals. We’re happy to discuss the broader picture if that’s relevant to your situation.

Is it too late to start treatment if I’m already in the frozen stage?

No. Treatment is valuable at every stage. In the frozen and thawing stages, there’s often significant opportunity to restore range of motion and reduce the time it takes to recover. Starting care, even partway through the condition, can meaningfully improve your trajectory.
