Pain after a proximal humerus fracture is most intense during the first two weeks and gradually improves over the following months. Most people experience significant relief by six to eight weeks as the bone begins to unite, though some degree of shoulder discomfort can persist for six months or longer depending on the severity of the fracture and how recovery is managed.
The First Two Weeks: Peak Pain
The initial days after a proximal humerus fracture are the most painful. Swelling, bruising, and inflammation around the break site make almost any arm movement excruciating. Your arm will typically be immobilized in a sling during this period, which helps with pain relief and protects the healing bone. Sleep is often difficult because lying flat puts pressure on the shoulder, and many people find they need to sleep propped up or in a recliner.
Despite the pain, gentle movement starts sooner than you might expect. Pendulum exercises, where you lean forward and let the arm swing passively, can begin within the first one to two weeks for most patients. Research on conservative treatment shows that starting exercises as soon as pain allows leads to faster recovery, less pain at three months, and no increased risk of the fracture shifting. One study found that patients immobilized for just one week had less pain and better function at three months compared to those immobilized for three weeks.
Weeks Two Through Six: Gradual Improvement
Pain starts to ease noticeably during this window as the initial inflammatory response settles down. By weeks three to four, most people can begin passive forward elevation exercises, often done lying on their back to keep the movement gentle. You’ll still have pain with certain movements, particularly reaching overhead or behind your back, but the constant, throbbing ache of the first two weeks fades considerably.
Around six weeks, the bone typically shows radiographic evidence of healing. This is the point where treatment shifts: if pins were placed surgically, they’re usually removed at four to six weeks. Active assisted exercises, where you use your good arm or a pulley to help move the injured shoulder, are generally added at this stage. Pain at rest is minimal for most people by this point, though activity-related soreness remains common.
Six Weeks to Three Months: Building Strength
Once bone union is progressing well, strengthening exercises start around three months after the injury. This phase can bring a temporary uptick in soreness as you push the shoulder to do more. The pain is different from the acute fracture pain, more of a deep muscular ache and stiffness from weeks of limited use. Physical therapy sessions may be recommended if pain is worse than expected or if range of motion isn’t improving at a normal pace.
Daily tasks like getting dressed, cooking, and light household chores become manageable for most people during this window, though lifting anything heavy remains off-limits. The shoulder fatigues quickly, and overdoing it on a good day can cause a flare of pain that lasts a day or two.
Three to Six Months: Residual Soreness
By three to six months, the fracture itself has largely healed, and most pain comes from stiffness, muscle weakness, and soft tissue tightness rather than the bone. Weather changes, sleeping on the affected side, and repetitive overhead movements are common triggers for lingering discomfort. Many people describe this phase as “manageable but annoying” rather than truly painful.
Driving offers a useful benchmark for recovery. After surgical treatment of a proximal humerus fracture, patients returned to driving at an average of about 16 weeks (roughly four months). However, the average time to drive completely free of shoulder pain was closer to 32 weeks, or about eight months. More complex fractures and complications added two to three months to that timeline.
Surgery vs. Conservative Treatment
Whether you had surgery or were treated with a sling and physical therapy alone doesn’t dramatically change the pain timeline. Recent systematic reviews and randomized trials have found no significant difference in functional outcomes between surgical and conservative treatment, even for displaced fractures. Surgery does carry a higher risk of complications both in the short term and the long term. About 3% of patients initially treated without surgery eventually need an operation within six months, typically because the fracture isn’t healing properly.
Certain health conditions increase the risk that conservative treatment won’t be enough. Obesity, diabetes, osteoporosis, and alcohol abuse are all associated with a higher chance of needing secondary surgery, which resets parts of the pain and recovery timeline.
Long-Term Pain After One Year
Most people have recovered the majority of their shoulder function by 12 months, but not everyone is completely pain-free. A long-term follow-up study tracked proximal humerus fracture patients for 13 years and found that how a patient was doing at one year strongly predicted their long-term outcome. The one-year evaluation predicted protracted pain with 71% accuracy and persistent shoulder dysfunction with 88% accuracy. In practical terms, if you still have significant pain at the one-year mark, it’s less likely to fully resolve on its own.
Some residual stiffness and mild aching with heavy use is common even in people who recover well. Full overhead strength and range of motion may never completely return to pre-injury levels, particularly in older adults or those with more complex fracture patterns. That said, the majority of people return to their normal daily activities and describe their shoulder as functional, even if it’s not quite the same as before.
What Affects How Long Your Pain Lasts
- Fracture complexity: A simple, non-displaced crack heals faster and hurts less than a fracture with multiple fragments or significant displacement. Four-part fractures can delay recovery by two to three months compared to simpler breaks.
- Age and bone health: Osteoporosis slows healing and increases the risk of complications that prolong pain.
- Early movement: Starting gentle exercises within the first two weeks, rather than staying completely immobilized, is consistently linked to less pain and better function at three months.
- Complications: Postoperative complications like infection, hardware problems, or loss of fracture position can add months to the pain timeline and may require additional procedures.
- Consistency with rehab: Skipping physical therapy or avoiding movement out of fear tends to increase long-term stiffness and pain rather than protect the shoulder.
