A.I. Health Assistant Causes for Weakness in One Hand

The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced weakness in one hand. This list does not constitute medical advice.

  1. 1.Carpal Tunnel Syndrome

    The carpal tunnel is a narrow passageway filled with ligament and bones at the base of your hand. It contains nerve and tendons. Sometimes, thickening from irritated tendons or other swelling narrows the tunnel and causes the nerve to be compressed. Symptoms usually start gradually, and as they worsen, grasping objects can become difficult.

    Recovery time varies depending on treatment.

  7. 7.Pinched Nerve in the Neck

    With age, disks separating the cervical vertebrae (which are the bones of your spine in your neck) lose height as well as lose water content, becoming stiffer. The vertebrae move closer together, and nerves that exit between these bones may be pinched, causing pain to travel down the nerve as it passes through the arm. The pain is usually sharp, and some people report a "pins and needles" sensation or even complete numbness.

    Majority of patients get better with time (weeks to months).

    Rarity:
    Common
    Top Symptoms:
    pain in one shoulder, spontaneous shoulder pain, pain that radiates down arm, pain in the back of the neck, severe shoulder pain
