What causes pain in the inner part of the left shoulder and clavicle?

In general, pain inside the left shoulder near the clavicle may be related to overexertion, poor dietary habits, clavicle fracture, rotator cuff injury, shoulder arthritis, and other factors. Patients are advised to follow medical instructions for symptomatic treatment. Specific analysis is as follows:

1. Overexertion

If one engages in heavy physical labor over a long period without adequate rest, overexertion can easily lead to muscle strain, which typically causes pain inside the left shoulder near the clavicle. Appropriate rest, along with local massage and manipulation, can help relieve symptoms.

2. Poor dietary habits

Long-term picky eating, avoiding vegetables, or skipping meals can lead to malnutrition. Malnutrition may result in calcium deficiency and osteoporosis, causing pain in the area of the left clavicle. It is recommended that patients improve their nutrition by consuming more foods rich in high-quality protein, such as eggs, milk, and beef.

3. Clavicle fracture

If the left clavicle suffers external impact leading to a fracture, patients may experience pain inside the left shoulder near the clavicle. According to medical advice, treatments such as figure-of-eight bandage immobilization or manual reduction may be used to alleviate symptoms.

4. Rotator cuff injury

A strong impact or blunt trauma to the clavicular area may cause rotator cuff injury, resulting in pain inside the left shoulder near the clavicle. Under medical guidance, patients may take medications such as celecoxib capsules or receive injections of prednisolone acetate to manage the condition.

5. Shoulder arthritis

In cases of shoulder arthritis, repeated inflammatory stimulation of the joint can cause local pain and swelling. When pain radiates to areas such as the forearm and neck, it often also leads to pain inside the left shoulder near the clavicle. Medications such as meloxicam tablets or diclofenac sodium sustained-release tablets may be used under medical supervision.

In addition, this pain may also be associated with factors such as periarthritis of the shoulder (frozen shoulder) or bone cysts. If patients experience discomfort, it is recommended to seek timely medical evaluation at a hospital to avoid delays in diagnosis and treatment.
