Most shoulder pain improves with a combination of rest, targeted icing or heating, and simple exercises you can do at home. The specific approach depends on whether your pain is new or has been lingering for weeks, since acute injuries and chronic stiffness respond to different strategies. Here’s what works, why it works, and how to do it right.
Identify What’s Causing Your Pain
The shoulder is the most mobile joint in your body, which also makes it one of the most vulnerable. The most common culprits behind shoulder pain are rotator cuff problems (irritation, partial tears, or full tears of the tendons that stabilize the joint), bursitis (inflammation of the fluid-filled cushions around the joint), and impingement syndrome, where soft tissues get pinched during overhead movements.
A few patterns can help you narrow it down. Pain on the outer side of your upper arm, especially when lifting your arm in an arc or lying on it at night, typically points to a rotator cuff issue. This is particularly common in people over 40. A catching or grinding sensation when you raise your arm overhead often signals impingement. Stiffness that makes it hard to reach behind your back or lift your arm at all could indicate frozen shoulder, which develops gradually over weeks or months.
First 72 Hours: Protect a New Injury
If your shoulder pain started after a fall, a hard workout, or a sudden awkward movement, treat it as an acute injury for the first three days. The goal during this window is to limit swelling and prevent further damage.
Rest the arm and avoid movements that reproduce the pain. A simple sling can help during the first 48 hours if the pain is significant. Apply an ice pack for 20 minutes every other hour during the first day or two, placing a thin cloth between the ice and your skin. Keep icing for at least 72 hours or until the swelling has clearly gone down. Compression is difficult to apply effectively around the shoulder, so don’t worry about wrapping it. And since your shoulder already sits above your heart, elevation takes care of itself.
Ice or Heat: Which One to Use
Getting this wrong is one of the most common mistakes people make. The rule is straightforward: ice for anything new, swollen, or inflamed; heat for anything stiff, tight, or chronic.
For a fresh injury, stick with ice for the first 72 hours. Apply it for 20 minutes at a time with at least an hour between sessions. Never place ice directly on bare skin. After the swelling has resolved, you can switch to heat to loosen the joint and ease lingering soreness. For chronic shoulder tension or stiffness that’s been around for weeks, heat is generally the better choice. Use a heating pad or warm towel for about 15 minutes at a time, again with an hour break between sessions. If your shoulder feels tight before a workout, heat can help improve flexibility, but always use ice after exercise, not heat.
Over-the-Counter Pain Relief
Anti-inflammatory medications can reduce both pain and swelling. Ibuprofen at 200 to 400 mg every six to eight hours (up to 1,200 mg per day) or naproxen at 250 mg every six to eight hours (up to 1,000 mg per day) are the standard options. These work best for short-term use during an acute flare. If you find yourself reaching for them daily after a week or two, that’s a sign the underlying problem needs more attention than medication alone can provide.
Exercises That Help the Most
Gentle movement is one of the most effective tools for shoulder pain relief, often more effective than rest alone once the initial acute phase has passed. The American Academy of Orthopaedic Surgeons recommends a progression from passive range-of-motion exercises to active strengthening. Here are three key exercises to start with.
Pendulum Swings
Lean forward and place your good hand on a table or counter for support. Let your painful arm hang straight down. Gently swing it forward and back, then side to side, then in small circles. Do 2 sets of 10 in each direction, five to six days per week. Keep your back straight and your knees slightly bent. This exercise uses gravity to gently decompress the joint without requiring your muscles to do the work.
Passive External Rotation
Hold a broomstick or dowel with both hands in front of you, elbows bent at 90 degrees and tucked against your sides. Use your good arm to push the stick horizontally, rotating your injured arm outward until you feel a stretch (not pain). Hold for 30 seconds, relax for 30 seconds, and repeat 4 times. Do this five to six days per week. Keep your hips facing forward and avoid twisting your torso.
Resistance Band External Rotation
Once the first two exercises feel comfortable, add light resistance. Tie a resistance band in a loop around a doorknob. Stand sideways to the door, holding the band with the hand of your affected arm, elbow bent and pinned to your side. Slowly rotate your forearm outward against the band’s resistance, then return slowly. Start with 3 sets of 8 and progress to 3 sets of 12 as you get stronger, three days per week. Squeeze your shoulder blades together as you pull.
A typical conservative rehab program runs 6 to 12 weeks, with noticeable improvement often starting within the first few weeks of consistent effort.
Fix Your Sleep Position
Shoulder pain at night is one of the most frustrating symptoms because poor sleep positions can make the problem worse. If you sleep on your back, place a folded blanket or low pillow under your affected arm to keep the shoulder supported and aligned. This takes pressure off the joint without requiring you to change positions entirely.
If you’re a side sleeper and your painful shoulder is on top, hug a pillow to keep that arm straight and in a neutral position rather than letting it droop across your body. If you tend to sleep on the painful side, switching to the other side or to your back will make the biggest difference. Stomach sleeping is the worst position for shoulders. Tucking your arm under the pillow, which most stomach sleepers do naturally, compresses the rotator cuff and sets the stage for chronic problems.
Adjust Your Desk Setup
Hours of poor posture at a desk can create or worsen shoulder pain, even without an obvious injury. A few specific adjustments make a meaningful difference. Keep your upper arms close to your body while typing, with your hands at or slightly below elbow level. If your keyboard or desk is too high, your shoulders shrug upward all day, creating tension and strain.
Place your monitor directly in front of you, about an arm’s length away (20 to 40 inches). A screen that’s off to one side forces you to twist, loading one shoulder unevenly. Keep your mouse on the same surface as your keyboard and within easy reach so you’re not extending your arm repeatedly throughout the day.
When Shoulder Pain Needs Medical Attention
Some shoulder symptoms require professional evaluation rather than home treatment. If your shoulder joint looks visibly deformed after a fall, if you can’t move your arm away from your body at all, or if the pain is severe and came on suddenly with noticeable swelling, go to urgent care or an emergency room.
Shoulder pain accompanied by chest tightness, difficulty breathing, or sweating can signal a heart attack. Call 911 immediately if you experience these symptoms together.
For pain that hasn’t improved after 6 to 12 weeks of consistent home care and exercises, a cortisone injection into the joint is one common next step. These injections reduce inflammation directly at the source and can provide relief lasting up to several months, often buying enough time for physical therapy to take full effect.
