Top 10 Pain in One Bicep Causes

  1. 1.Brachial Plexopathy

    The brachial plexus is a complex nerve network located in the upper chest deep to the collar bone, which supplies the shoulder, arm, forearm, and hand. Damage to the brachial plexus is usually due to mechanical injury or trauma, and can interfere with normal nerve function causing numbness, pain, and/or weakness.

    You should visit your primary care physician to discuss these symptoms. It is likely the doctor will perform a thorough physical exam, and in many cases refer you to a specialist, physical therapist, or both. A professional evaluation is very important, as surgical treatment might be required for a brachial plexus nerve injury.

    Rarity:
    Common
    Top Symptoms:
    pain in one arm, shoulder pain that shoots to the arm, arm weakness, numbness in one arm, shoulder pain
    Urgency:
    Primary care doctor
  2. 2.Rotator Cuff Tendonitis

    Impingement syndrome is a common shoulder condition seen in aging adults. The tendons of rotator cuff muscles, whose action is to rotate the arm such such as during a tennis swing, pass in a narrow space between two bones in the shoulder. When the space becomes too narrow, which can happen as a result of an overuse injury, pain may develop as the tendons rub against the bones.

    You should visit your primary care physician who will coordinate care with a muscle and bone specialist (orthopedic surgeon). Treatments for impingement syndrome involve rest, over-the-counter pain medication, steroid injections, physical therapy, and surgery in rare, serious cases.

    Rarity:
    Common
    Top Symptoms:
    pain in one shoulder, dull, achy shoulder pain, shoulder pain that gets worse at night, difficulty moving the shoulder, shoulder pain from overuse
    Symptoms that always occur with rotator cuff tendonitis:
    pain in one shoulder
    Urgency:
    Primary care doctor
  3. 3.Biceps Tendon Rupture

    The biceps is the muscle in the front of the upper arm. Its main action is to flex the arm. The biceps muscle collects in a tendon that inserts into the radius (one of the bones of the forearm). Sometimes, if lifting something heavy or rapidly putting weight on the arm, the biceps tendon may pull away from the bone. Biceps tendon ruptures are classified as either partial or complete ruptures, depending on if the tendon pulled away only somewhat, or completely.

    You should visit your primary care physician who will coordinate your care with a muscle and bone specialist (orthopedic surgeon). The treatment for biceps tendon rupture is surgery.

    Rarity:
    Uncommon
    Top Symptoms:
    pain in one shoulder, pain in the front of the shoulder, spontaneous shoulder pain, dull, achy shoulder pain, shoulder pain that gets worse at night
    Symptoms that always occur with biceps tendon rupture:
    pain in the front of the shoulder, pain in one shoulder
    Urgency:
    Primary care doctor
  4. 4.Biceps Tendonitis

    The biceps is the muscle in the front of the upper arm. Its main action is to flex the arm. The beginning of the muscle is a tendon that passes in front of the shoulder. Problems with the tendon can arise due to impingement (where the tendon gets compressed by surrounding structures) or inflammation due to overuse of the shoulder. People with this condition experience a deep, throbbing ache in the front of the shoulder.

    You should visit your primary care physician who will coordinate care with a physical therapist. First-line treatments for this condition involve rest from activity, physical therapy, and over-the-counter pain medication.

    Rarity:
    Rare
    Top Symptoms:
    pain in one shoulder, pain in the front of the shoulder, spontaneous shoulder pain, dull, achy shoulder pain, shoulder pain that gets worse at night
    Symptoms that always occur with biceps tendonitis:
    pain in the front of the shoulder
    Urgency:
    Primary care doctor
  5. 5.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.

    Early diagnosis and treatment are important to prevent permanent nerve damage. Your doctor will diagnose carpal tunnel syndrome with a physical exam and special nerve tests. Treatment includes resting your hand, splints, pain and anti-inflammatory medicines. If symptoms do not improve with these less invasive treatments, your physician may recommend surgery.

    Rarity:
    Common
    Top Symptoms:
    spontaneous shoulder pain, hand weakness, wrist pain, pain in one hand, weakness in one hand
    Urgency:
    Primary care doctor

  6. 6.Neuralgic Amyotrophy

    Hereditary neuralgic amyotrophy is a disorder characterized by episodes of severe pain and muscle wasting (amyotrophy) in one or both shoulders and arms. Neuralgic pain is felt along the path of one or more nerves and often has no obvious physical cause. The network of nerves involved in hereditary neuralgic amyotrophy, called the brachial plexus, controls movement and sensation in the shoulders and arms.

    You should visit your primary care physician who will likely coordinate care with a nerve specialist (neurologist). Treatment for this condition involves pain management with medication, as well as physical therapy.

    Rarity:
    Rare
    Top Symptoms:
    arm weakness, pain in the back of the neck, general numbness, severe shoulder pain, difficulty moving the shoulder
    Urgency:
    Primary care doctor
  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.

    You should visit your primary care physician who will coordinate your care with a muscle and bone specialist (orthopedic surgeon). Cervical radiculopathy is treated with pain medication, soft neck collars, and physical therapy.

    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
    Symptoms that always occur with pinched nerve in the neck:
    pain that radiates down arm
    Urgency:
    Primary care doctor
  8. 8.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.

    Rarity:
    Uncommon
    Top Symptoms:
    nausea, abdominal pain (stomach ache), pain in one arm, being severely ill, shortness of breath
    Urgency:
    Emergency medical service
  9. 9.Repetitive Strain Injury of the Upper Arm

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

    You do not need treatment, just rest from your overuse. Wearing a brace and physical therapy might be helpful.

    Rarity:
    Uncommon
    Top Symptoms:
    upper arm pain from overuse, upper arm weakness, upper arm numbness
    Symptoms that always occur with repetitive strain injury of the upper arm:
    upper arm pain from overuse
    Symptoms that never occur with repetitive strain injury of the upper arm:
    upper arm injury, severe upper arm pain
    Urgency:
    Self-treatment
  10. 10.Shoulder Bruise

    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 shoulder are common, given how exposed this area of the body is.

    You can treat this at home with R.I.C.E - rest (exercise as tolerated), ice (10-20 minutes at a time), compression (this is pretty optional), and elevation (difficult for this part of the body).

    Rarity:
    Rare
    Top Symptoms:
    constant shoulder pain, pain in one shoulder, shoulder injury, shoulder pain from an injury, swelling of one shoulder
    Symptoms that always occur with shoulder bruise:
    shoulder pain from an injury, shoulder injury, constant shoulder pain
    Urgency:
    Self-treatment
