Why does my elbow ache when it is bent?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Elbow pain when bent is often caused by strained or injured tendons, nerves, or ligaments within the joint. Common culprits include overuse (such as repetitive gripping or lifting), minor injuries, or instability in the elbow joint itself. Conditions like tennis elbow, golfer's elbow, cubital tunnel syndrome, or bursitis can all trigger discomfort during bending. Identifying the root cause is key to finding relief and preventing further damage.

Because elbow pain has many possible causes—ranging from mild inflammation to nerve compression—guessing can delay proper care. Take a free, instant, online symptom check to better understand what may be behind your pain and confidently navigate your next steps.

Explanation

The elbow is a complex joint where bones, muscles, tendons, and ligaments work together. When you bend your elbow, these parts move and help your arm work. Sometimes, when one of these parts is strained or injured, it may develop pain. Tennis elbow, as described in one research study, happens due to overuse, which can cause tiny tears in the tendon that attaches your muscles to your bone. In another situation, if the ulnar nerve is compressed during flexion, it can cause pain and tingling. If you're experiencing elbow discomfort, try our free symptom checker to better understand what might be causing your pain. It is important to rest the elbow, avoid activities that worsen the pain, and seek a healthcare provider's advice if the pain continues. These steps help manage inflammation and improve healing over time.
