What could be the reason I can't bend my elbow without pain?

Reviewed by Yoshinori Abe, MD

Internal Medicine

A stiff elbow that hurts when bending is often caused by injury, overuse, or inflammation affecting the elbow joint, surrounding muscles, or tendons. Common culprits include tendonitis, bursitis, arthritis, sprains, or repetitive strain. Symptoms may include swelling, reduced range of motion, and sharp or aching pain when flexing the arm.

Because elbow pain can stem from many different conditions—some minor, others requiring medical attention—it's important to identify the likely cause early. Taking a free, instant, online symptom check can help you better understand what's driving your discomfort, narrow down possible conditions, and guide your next steps toward relief and recovery.

Explanation

If you haven't experienced a specific injury, pain when bending the elbow typically indicates joint stiffness. This stiffness can result from injuries, inflammatory conditions like tendinitis, or arthritis in the joint. Repetitive motions in sports or work activities may lead to overuse injuries, causing stiffness and pain. Conditions such as tennis elbow or golfer's elbow—which affect the tendons on either side of the elbow—can also cause pain and restrict joint mobility. If you cannot bend your elbow after a fall or injury, you may have a broken bone or dislocated joint. To better understand what might be causing your elbow pain, try our free AI symptom checker and see a healthcare provider for an evaluation to determine the cause and get personalized advice on relieving pain and improving mobility.
