Introduction
Repetitive muscle tension or acute injury may lead to inflammation of the biceps tendon, resulting in tendonitis. The inflammatory response can compress nerve endings, causing pain within the biceps tendon, possibly accompanied by tenderness and restricted movement. It is recommended to treat under medical supervision with medications such as indomethacin tablets, diclofenac sodium tablets, or celecoxib capsules.

Under normal circumstances, pain in the tendons of the biceps brachii may be caused by poor posture, overuse, tendonitis, periarthritis of the shoulder, or neuropathy. If discomfort occurs, it is recommended to seek medical attention promptly. Specific analyses are as follows:

1. Poor Posture

Prolonged poor posture, such as looking down at mobile phones or computers, may lead to tension in the neck, shoulder, and upper arm muscles, which can affect the tendons of the biceps brachii and cause pain within the muscle. This is often accompanied by symptoms such as stiffness and pain in the neck and shoulders. It is recommended to improve posture, take regular breaks, and perform stretching exercises for the neck and shoulders.

2. Overuse

Excessive use of the biceps brachii can place excessive stress on muscle fibers and tendons, leading to micro-tears or inflammatory responses, thereby causing tendon pain in the biceps. Typically, no other significant discomfort is present. Adequate rest is advised, along with avoiding repetitive activities that trigger pain.

3. Tendonitis

Repeated muscle strain or acute injury may cause inflammation of the biceps tendon, resulting in tendonitis. The inflammatory response may compress nerve endings, leading to pain in the biceps tendons, possibly accompanied by tenderness and restricted movement. It is recommended to follow medical advice and use medications such as indomethacin tablets, diclofenac sodium tablets, or celecoxib capsules for treatment.

4. Periarthritis of the Shoulder

Trauma or impact may trigger periarthritis of the shoulder, and the inflammatory response may affect the tendons of the biceps brachii, causing pain. This is commonly associated with shoulder pain and limited range of motion. It is advisable to relieve pain under medical guidance through physical therapies such as heat application, massage, or acupuncture.

5. Neuropathy

Damage to the brachial plexus or its branches may lead to neuropathy. Nerve injury or compression can disrupt neural conduction, causing pain in the biceps tendons, along with symptoms such as tingling, numbness, and muscle weakness. It is recommended to follow medical advice and use medications such as aspirin extended-release tablets, acetaminophen tablets, or ibuprofen extended-release capsules for treatment.

In daily life, appropriate physical exercise can be increased to enhance physical strength and boost immune function.
