A.I. Health Assistant Causes for Upper Arm Pain

The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced upper arm pain. 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.

    Rarity:
    Uncommon
    Top Symptoms:
    pain in one arm, shoulder pain that shoots to the arm, arm weakness, numbness in one arm, shoulder pain
    Symptoms that never occur with brachial plexopathy (shoulder nerve issue):
    pain in the front middle part of the neck
    Urgency:
    Primary care doctor
  2. 2.Repetitive Strain Injury of the Upper Arm

    Repetitive strain injury of the upper arm is caused by consistent repetitive use.

  3. 3.Bruised Tricep

    A bruise is the damage of the blood vessels that return blood to the heart (the capillaries and veins), which causes pooling of the blood. This explains the blue/purple color of most bruises. Bruises of the tricep are common, often due to minor injury.

    Bruises tend to begin healing within one week.

    Rarity:
    Rare

    Unfortunately, CRPS is a life-long condition that may get worse over time.

    Rarity:

    Top Symptoms:
    pain in one arm, pain in one leg, pain in one foot, tremor, fatigue
    Urgency:

  7. 7.Upper Arm Bone Infection (Osteomyelitis)

    Osteomyelitis of the upper arm is a bacterial or fungal infection of the bone, typically caused by Staph Aureus (40-50% of the time). It is difficult to diagnose as the infection can come from a break in the skin at the area or anywhere else in the body that spreads by blood.
