Elbow pain when bending can be caused by several common conditions involving tendons, nerves, or joint issues. The most frequent causes include:
- Tennis elbow (lateral epicondylitis): inflammation of tendons on the outside of the elbow due to repetitive wrist and arm motions, causing pain when bending or gripping objects.
- Golfer's elbow (medial epicondylitis): similar tendon inflammation but on the inside of the elbow, often from repetitive wrist flexion or gripping.
- Elbow bursitis: inflammation of fluid-filled sacs cushioning the joint, often causing swelling and pain that worsens when bending.
- Arthritis: both osteoarthritis and rheumatoid arthritis can cause pain, stiffness, and difficulty moving the elbow gradually.
- Ulnar nerve entrapment (cubital tunnel syndrome): nerve compression causing pain, numbness, or tingling that worsens with bending.
- Tendonitis or tears in the biceps tendon attaching near the elbow can also cause pain especially during bending.
These conditions often arise from repetitive strain, overuse, injury, or inflammation of tendons, nerves, or joint tissues. If the pain is persistent, worsening, or accompanied by swelling or numbness, consulting a healthcare professional is advisable for accurate diagnosis and treatment options.
