How to Fix Shoulder Pain: Causes, Exercises & Relief

Most shoulder pain improves with a combination of rest, targeted exercises, and over-the-counter anti-inflammatory medication. About 75% of people with rotator cuff tears who follow a structured physical therapy program improve enough to avoid surgery entirely. The key is identifying what’s causing your pain, since the fix depends heavily on the underlying problem.

What’s Likely Causing Your Pain

Shoulder problems generally fall into four categories: tendon inflammation or tears, impingement, instability, and arthritis. The most common culprit is some combination of the first two, especially if your pain started gradually or worsens when you raise your arm overhead.

Tendinitis develops when the tendons connecting your rotator cuff muscles to bone become inflamed. It can be acute, from a sudden burst of overhead activity like painting a ceiling or throwing a ball, or chronic, building slowly from years of repetitive use or normal aging. Bursitis often shows up alongside tendinitis. The bursa is a small fluid-filled sac that cushions your rotator cuff, and when it swells, even basic movements like combing your hair or reaching behind your back become painful.

Impingement happens when the bony tip of your shoulder blade pinches the soft tissues underneath it every time you lift your arm. Over time, this pinching irritates the rotator cuff tendons and bursa, creating a cycle of inflammation and pain that gets worse with overhead reaching. If your shoulder hurts most when you lift your arm to the side or above shoulder height, impingement is a likely cause.

Tendon tears are more serious. They can happen suddenly from a fall or develop gradually as tendons weaken with age. A partial tear goes partway through the tendon; a complete tear pulls it fully off the bone. Pain with weakness, especially when lowering your arm from a raised position, often points toward a tear.

Exercises That Build Your Shoulder Back Up

Exercise is the single most effective treatment for the majority of shoulder pain. A good program progresses through three phases: gentle range-of-motion work, isometric holds (where you push against resistance without moving), and strengthening with light weights or resistance bands.

Isometric internal and external rotation: Stand next to a wall or doorframe and press the inside or outside of your forearm into it, as if trying to rotate your arm but the wall won’t let you. Hold each push for 10 seconds, and repeat 10 times. This activates the rotator cuff without stressing the joint through movement, making it a safe starting point when your shoulder is still irritable.

Scaption raises: Hold a light weight in each hand with your thumbs pointing up. Raise your arms forward and slightly out to the sides, forming a V shape, until they reach about shoulder height. Lower slowly. Aim for three sets of 10 repetitions. If you can tolerate it, go straight through to 30 reps without stopping. This exercise strengthens the muscles that stabilize your shoulder blade and rotator cuff during overhead movement.

Side-lying external rotation: Lie on your unaffected side with a light dumbbell in your top hand. Keep your elbow bent at 90 degrees and pinned to your side, then rotate your forearm toward the ceiling. Three sets of 10, or 30 straight through if your shoulder allows it. This targets the external rotators, which are typically the weakest link in shoulder impingement.

Consistency matters more than intensity. A four-month physical therapy program is typical for rotator cuff problems, though many people notice meaningful improvement within the first few weeks.

Managing Pain and Inflammation

Over-the-counter ibuprofen at 200 to 400 mg every four to six hours (no more than 1,200 mg per day) can reduce inflammation and take the edge off pain while you work on strengthening. Ice applied for 15 to 20 minutes several times a day helps during the first few days of a flare-up. After the acute phase settles, heat before exercise can loosen stiff tissues.

If oral medication and exercises aren’t enough, a cortisone injection into the shoulder joint can provide relief lasting up to several months. These injections are generally limited in frequency because repeated cortisone exposure can damage cartilage over time. They work best as a bridge, reducing pain enough to let you participate in physical therapy rather than serving as a long-term solution on their own.

How to Sleep Without Making It Worse

Nighttime pain is one of the most frustrating parts of a shoulder problem. The goal is to keep your shoulder from dropping forward or downward, which compresses the already irritated structures inside the joint.

If you sleep on your back, place a folded blanket or low pillow under your affected arm to support it and keep the shoulder aligned with your body. If you’re a side sleeper, try sleeping with the painful shoulder facing up and use a pillow to keep that arm in a straight, neutral position rather than letting it fall across your chest. Stomach sleeping is the worst option for shoulder pain. Tucking your arm under the pillow overhead puts enormous stress on the rotator cuff and can either worsen an existing problem or create a new one.

When Pain Doesn’t Improve: Frozen Shoulder

If your shoulder gradually becomes stiffer over weeks to months, you may be dealing with frozen shoulder, a condition where the tissue surrounding the joint thickens and tightens. It progresses through three distinct stages.

The freezing stage lasts six weeks to nine months. Pain increases gradually, often worse at night, and your range of motion steadily shrinks. The frozen stage follows, lasting two to six months. Pain may actually decrease, but stiffness peaks, making daily tasks like reaching into a cabinet or fastening a seatbelt difficult. Finally, the thawing stage brings slow recovery of motion over six months to two years.

The total course can stretch past two years. Gentle stretching and physical therapy throughout can speed recovery and prevent permanent stiffness, but frozen shoulder requires patience. Aggressive stretching during the freezing stage often makes things worse.

What Surgery and Recovery Look Like

Surgery is typically reserved for complete rotator cuff tears, significant structural damage, or pain that hasn’t responded to several months of conservative treatment. Since three out of four people with rotator cuff tears improve with physical therapy alone, surgery is a last resort for most.

If you do need rotator cuff repair, expect to wear a sling nearly full-time for the first four weeks, including while sleeping. The sling comes off around week four, and passive range-of-motion exercises begin. Driving typically resumes between six and eight weeks after surgery. Serious strengthening starts around month three, and if you play sports, you can begin sport-specific training between months three and six under guidance from a physical therapist.

Red Flags That Need Immediate Attention

Most shoulder pain is not an emergency, but certain combinations of symptoms are. Shoulder pain paired with chest tightness, difficulty breathing, or sweating can signal a heart attack, and you should call 911 immediately.

After a fall or accident, get to urgent care or an emergency room if your shoulder joint looks visibly deformed, you can’t move your arm away from your body at all, the pain is severe, or you develop sudden swelling. These signs suggest a dislocation, fracture, or major tendon rupture that needs prompt evaluation.
