Differential Diagnosis for Tingling Sensation in the Right Arm

  • Single Most Likely Diagnosis

    • Cervical Radiculopathy: This condition, often caused by a herniated disk or bone spurs in the cervical spine, can compress nerves leading to the arm, resulting in tingling sensations. It is a common cause of arm tingling and is often associated with neck pain or trauma.
  • Other Likely Diagnoses

    • Carpal Tunnel Syndrome: Compression of the median nerve in the wrist can cause tingling in the arm, particularly in the thumb, index, and middle fingers. It is often associated with repetitive motion or wrist trauma.
    • Thoracic Outlet Syndrome: Compression of the nerves or blood vessels that pass through the thoracic outlet (the space between the collarbone and first rib) can cause tingling in the arm. It is often associated with poor posture, trauma, or anatomical abnormalities.
    • Peripheral Neuropathy: Damage to the peripheral nerves can cause tingling sensations in the arm. It can be caused by various factors, including diabetes, vitamin deficiencies, or certain medications.
  • Do Not Miss Diagnoses

    • Stroke or Transient Ischemic Attack (TIA): Although less likely, a stroke or TIA can cause sudden tingling sensations in one arm. It is crucial to consider this diagnosis, as prompt treatment is essential to prevent further damage.
    • Multiple Sclerosis: This chronic disease can cause tingling sensations in the arms due to damage to the central nervous system. Although less common, it is essential to consider this diagnosis, as early treatment can improve outcomes.
  • Rare Diagnoses

    • Guillain-Barré Syndrome: A rare autoimmune disorder that can cause tingling sensations in the arms, often following an infection. It can progress to paralysis if left untreated.
    • Tumor or Cyst: A tumor or cyst compressing nerves in the neck or arm can cause tingling sensations. Although rare, it is essential to consider this diagnosis, as prompt treatment can improve outcomes.
    • Vitamin Deficiencies: Deficiencies in vitamins such as B12 or vitamin D can cause tingling sensations in the arms. Although rare, it is essential to consider this diagnosis, as supplementation can resolve symptoms.
