Top 6 Numbness in the Back Side of the Forearm Causes

  1. 1.Heart Attack in a Woman

    Most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat - called an arrhythmia - that causes a severe decrease in the pumping function of the heart.

    You should call 911.

  4. 4.Neck Sprain

    The neck is made up of 7 bones held together by muscles and ligaments. Any stretch of these muscles or ligaments causes a sprain, which will cause pain and affect your ability to move the neck.

    You can treat a neck sprain like most sprains - rest (a neck collar if necessary), ice (for 10-20 minutes at a time), pain relievers (like ibuprofen), and gentle massage.

    Rarity:
    Common
    Top Symptoms:
    headache, shoulder pain, pain in the back of the neck, difficulty moving the neck, neck pain
    Symptoms that always occur with neck sprain:
    pain in the back of the neck
    Symptoms that never occur with neck sprain:
    fever
    Urgency:
    Phone call or in-person visit
  5. 5.Stroke or Tia (Transient Ischemic Attack)

    A stroke is a medical emergency. Strokes happen when blood flow to the brain is stopped.

    You needs to go to the hospital by ambulance or as soon as possible. The longer you wait, the fewer treatment options available and the worse the outcome.

    Rarity:
    Rare
    Top Symptoms:
    being severely ill, new headache, stiff neck, dizziness, vision changes
    Symptoms that never occur with stroke or tia (transient ischemic attack):

    Urgency:

  6. 6.Hyperparathyroidism

    Hyperparathyroidism is a disorder in which the parathyroid glands in the neck are overactive and produce too much parathyroid hormone (PTH). This hormone causes calcium to be released from bones and into the blood.

    You should visit your primary care physician who will likely coordinate care with a specialist. Hyperparathyroidism is usually treated with surgery that involves removing the glands to make sure your blood calcium levels remain normal.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, depressed mood, abdominal pain (stomach ache), irritability, nausea or vomiting
    Urgency:
    Primary care doctor
