[24F] Experiencing periodic arm numbness and dizziness

Patient Description

A 24-year-old female reports periodic episodes of complete numbness in the left arm, lasting 2 to 5 minutes, occurring 3-4 times a month. The numbness, which initially affected a smaller area, has progressed over 6 months to involve the entire arm up to just under the shoulder. The patient has found that hitting the arm seems to alleviate the numbness. Accompanying symptoms include occasional dizziness. There is no associated severe headache, vision changes, speech difficulties, or sudden weakness. The patient has no known drug allergies, is not on any medications, and has no significant past medical history or family history of cardiovascular diseases. No recreational or substance abuse history is reported.

Arora's Assessment

What might be happening

Based on your symptoms, several conditions could be causing your left arm numbness:

  • Peripheral Neuropathy: This condition results from damage to the peripheral nerves, often causing weakness, numbness, and pain, usually in your hands and feet. It can also affect other areas of your body, like your arm. Peripheral neuropathy can result from traumatic injuries, infections, metabolic problems, inherited causes, and exposure to toxins.

    • Treatment usually involves managing the condition causing your neuropathy. In some cases, over-the-counter pain relievers can help. For more severe symptoms, your doctor might recommend prescription medications.

  • Thoracic Outlet Syndrome (TOS): This group of disorders occurs when blood vessels or nerves in the space between your collarbone and your first rib (thoracic outlet) become compressed. This can cause pain in your shoulders and neck and numbness in your fingers. Common causes of TOS include physical trauma from a car accident, repetitive injuries from job- or sports-related activities, certain anatomical defects (such as having an extra rib), and pregnancy.

    • Treatment for TOS usually involves physical therapy and pain relief measures. Most people improve with these approaches. In some cases, however, your doctor might recommend surgery.

  • Stroke or Transient Ischemic Attack (TIA): Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body, can be a sign of a stroke or TIA. However, these are usually accompanied by other symptoms such as confusion, trouble speaking or understanding speech, difficulty seeing in one or both eyes, difficulty walking, dizziness, loss of balance or coordination, or severe headache with no known cause.

    • Treatment depends on whether you're having a stroke or TIA and, if you're having a stroke, what type it is. Treatment usually begins in the hospital. After you leave the hospital, you might continue treatment at a rehabilitation center.

What you can do

You should seek immediate medical attention. Numbness in the arm, especially when accompanied by dizziness and weakness, can be a sign of serious conditions such as a stroke. While your symptoms do not align perfectly with a typical stroke, it is better to be safe and get evaluated immediately.

What you should look out for

If you experience any of the following symptoms, you should seek immediate medical attention:

  • Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body
  • Sudden confusion, trouble speaking or understanding speech
  • Sudden trouble seeing in one or both eyes
  • Sudden trouble walking, dizziness, loss of balance or coordination
  • Sudden severe headache with no known cause
