Differential Diagnosis for Forearm Pain when Curling Weights
Single Most Likely Diagnosis
- Medial Epicondylitis (Golfer's Elbow): This condition is characterized by inflammation of the tendons that attach to the medial epicondyle of the humerus, leading to pain and discomfort in the forearm, especially when performing activities that involve flexion of the wrist or curling movements.
Other Likely Diagnoses
- Lateral Epicondylitis (Tennis Elbow): Although more commonly associated with extension movements, lateral epicondylitis can also cause forearm pain during activities that involve gripping or curling, due to the inflammation of the tendons attaching to the lateral epicondyle.
- Strain of the Forearm Muscles: Overuse or direct injury to the muscles of the forearm can lead to strain, causing pain during activities like weight curling.
- Radial Tunnel Syndrome: Compression of the radial nerve as it travels through the forearm can cause pain in the back of the hand or forearm, especially with activities that involve wrist extension or gripping, but can also be exacerbated by curling movements.
Do Not Miss Diagnoses
- Compartment Syndrome: A serious condition where increased pressure within the compartments of the forearm can lead to nerve and muscle damage. Although less common, it is crucial to consider due to its potential for severe and lasting damage if not promptly treated.
- Fracture or Stress Fracture: A fracture or stress fracture in the forearm bones (radius or ulna) can cause pain that worsens with activity, including curling weights. Missing this diagnosis could lead to further injury or improper healing.
Rare Diagnoses
- Tumor or Cyst: Rarely, a tumor or cyst in the forearm can cause pain and discomfort, especially if it compresses nerves or interferes with muscle function.
- Infection: An infection in the forearm, such as osteomyelitis or a soft tissue infection, can cause pain, swelling, and warmth, and is a rare but serious condition that needs prompt medical attention.
- Vascular Conditions: Conditions affecting the blood vessels, such as thoracic outlet syndrome or vascular malformations, can cause forearm pain during exercise due to altered blood flow, but are less common causes of pain when curling weights.
