Differential Diagnosis for Elbow Pain Radiating to Forearm
- Single Most Likely Diagnosis
- Lateral Epicondylitis (Tennis Elbow): This is the most likely diagnosis given the patient's occupation in construction, which involves repetitive motions, and the presentation of severe elbow pain radiating into the forearm. The patient's symptoms and the fact that the pain is worsening despite taking Tylenol support this diagnosis.
- Other Likely Diagnoses
- Medial Epicondylitis (Golfer's Elbow): Although less common than lateral epicondylitis, medial epicondylitis could also be a consideration given the patient's occupation and the presence of elbow pain. However, the pain typically radiates to the medial (inner) aspect of the forearm.
- Radial Head Fracture: A fracture could be a possibility, especially if the patient has experienced a fall or direct trauma to the elbow. However, the absence of a reported traumatic event and the description of the pain make this less likely.
- Bursitis: Elbow bursitis, such as olecranon bursitis, could cause pain and swelling around the elbow but typically presents with more pronounced swelling and redness.
- Do Not Miss Diagnoses
- Septic Arthritis: Although less likely, septic arthritis is a serious condition that requires immediate attention. The presence of erythema, worsening pain, and systemic symptoms such as fever could indicate septic arthritis.
- Osteomyelitis: Bone infection could present with pain, erythema, and swelling. Given the patient's occupation and potential for minor, unnoticed traumas, this is a diagnosis that should not be missed.
- Cubital Tunnel Syndrome: This condition involves compression of the ulnar nerve and could present with forearm pain and paresthesias. It's less likely given the description but should be considered, especially if there are symptoms of nerve compression.
- Rare Diagnoses
- Tumors (e.g., osteochondroma, osteosarcoma): Although rare, bone tumors could cause elbow and forearm pain. These would be considerations if the patient does not respond to typical treatments for more common conditions.
- Inflammatory Arthritis (e.g., rheumatoid arthritis, psoriatic arthritis): These conditions could cause elbow pain and swelling but typically present with a more systemic symptomatology and involvement of other joints.
- Neurological Conditions (e.g., radiculopathy): Conditions affecting the nerves, such as a radiculopathy from a cervical spine issue, could cause forearm pain but would likely be accompanied by other neurological symptoms such as numbness, tingling, or weakness.
