A.I. Health Assistant Causes for Significant Loss of Muscle Mass in One Arm

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

  1. 1.Brachial Plexopathy (Shoulder Nerve Issue)

    The brachial plexus is a complex nerve network located in the upper chest and shoulder region. Nerves can be explained as 'electric wires' of the body, passing through signals from the brain to the spinal cord and from the spinal cord to the muscles. The brachial plexus is a bundle of nerves that lies deep to the collar bone, which supplies the shoulder, arm, forearm, and hand. When this bundle of nerves is (partially) damaged, one speaks of a 'plexopathy'. Several causes of damage can be injury or forceful trauma, inflammation or infection. A commonly known cause is sports injury in contact sports like football and rugby. Symptoms can include pain, burning, numbness and weakness in the shoulder and arm on one side, sometimes shooting through the arm to the hand. An acute (sports) injury that causes this condition is often called 'burners' or 'stingers' because of the burning and stinging type of pain. When the cause is inflammation of the nerves, it is often called the Parsonage-Turner syndrome.

    The severity of this condition is highly variable, and dependent on the amount of damage caused to the nerves. Brachial plexus injury following surgery usually has a good prognosis. Recovery times range from 2 weeks to 2 years.

    Top Symptoms:
    pain in one arm, shoulder pain that shoots to the arm, arm weakness, numbness in one arm, shoulder pain

    Urgency:

  2. 2.Chronic Idiopathic Peripheral Neuropathy

    Nerve damage in the limbs can be caused by diabetes, toxic substances, immune system issues and low vitamin levels. However, in about one of every four cases no cause can be found and then the condition is called 'idiopathic'. Symptoms of nerve damage can be (burning) pain sensations, numbness, tingling and weakness in hands, feet or lower legs.

    This is a chronic condition.

    Rarity:

    Top Symptoms:
    distal numbness, muscle aches, joint stiffness, numbness on both sides of body, loss of muscle mass
