Differential Diagnosis for Right Bicep Pain
Single Most Likely Diagnosis
- Bicipital Tendinitis: This is the most common cause of bicep pain, often resulting from overuse or repetitive strain on the bicep tendon, leading to inflammation and pain.
Other Likely Diagnoses
- Bicep Strain: A strain or pull in the bicep muscle can cause pain, especially if it occurs suddenly due to heavy lifting or bending.
- Bursitis: Inflammation of the bursae around the shoulder or elbow can radiate pain to the bicep area.
- Radial Neuropathy: Compression or injury to the radial nerve can cause pain, weakness, or numbness in the bicep area.
Do Not Miss Diagnoses
- Brachial Artery Aneurysm or Thrombosis: Although rare, a ruptured aneurysm or thrombosis in the brachial artery can cause severe arm pain, including the bicep area, and is a medical emergency.
- Osteosarcoma or Other Bone Cancers: Bone tumors can cause pain in the affected limb, including the bicep area, and are critical to diagnose early.
- Infectious Myositis: A bacterial or fungal infection of the muscle can cause severe pain, swelling, and redness, requiring prompt antibiotic treatment.
Rare Diagnoses
- Parsonage-Turner Syndrome: A rare condition characterized by sudden onset of severe pain in the shoulder and arm, followed by weakness and atrophy of the muscles.
- Amyotrophic Lateral Sclerosis (ALS): A progressive neurological disease that can cause muscle weakness, atrophy, and pain, including in the bicep area.
- Polymyalgia Rheumatica: An inflammatory condition that can cause muscle pain and stiffness, often in the shoulders and upper arms.
