Differential Diagnosis for Arm Pain with Gripping
Single most likely diagnosis
- Lateral Epicondylitis (Tennis Elbow): This condition is characterized by pain on the outer aspect of the elbow, which can radiate down the arm and is exacerbated by gripping activities. The onset after triceps exercises, which can involve gripping, makes this a highly plausible diagnosis.
Other Likely diagnoses
- Medial Epicondylitis (Golfer's Elbow): Although less common than lateral epicondylitis, medial epicondylitis causes pain on the inner aspect of the elbow and can be related to activities involving gripping. It's a possible diagnosis if the pain is more medially located.
- Strain of the Triceps or Forearm Muscles: Overuse or improper technique during triceps exercises could lead to a strain in the muscles of the forearm or triceps, causing pain with gripping.
- Cubital Tunnel Syndrome: This condition involves compression of the ulnar nerve at the elbow, leading to pain, numbness, and weakness in the hand and arm, especially with activities that involve flexion of the elbow or gripping.
Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Acute Compartment Syndrome: Although rare, this is a medical emergency that requires immediate attention. It involves increased pressure within a muscle compartment, leading to pain, especially on palpation, and can result from intense exercise. Missing this diagnosis can lead to permanent muscle and nerve damage.
- Radial Head Fracture: A fracture of the radial head can occur from a fall onto an outstretched hand or from repetitive strain and could present with pain on gripping if the fracture affects the radiocapitellar joint.
Rare diagnoses
- Tumors (e.g., Osteoid Osteoma, Soft Tissue Sarcomas): Although extremely rare, tumors can cause localized pain that might be exacerbated by activity. They would be considered if more common diagnoses are ruled out and the pain persists or worsens over time.
- Infectious or Inflammatory Conditions (e.g., Osteomyelitis, Cellulitis): These conditions can cause arm pain but are typically accompanied by other symptoms such as fever, redness, and swelling. They are less likely without a clear infectious source or systemic symptoms but should be considered in the appropriate clinical context.
