Introduction
A sprained foot with a painful area on the dorsum upon palpation is mainly caused by reasons such as muscle strain, ligament injury, hematoma, joint dislocation, and fracture. If discomfort occurs, seek medical attention promptly and follow the guidance of a physician regarding general treatment and medication. Maintain a balanced diet and consume adequate calcium- and vitamin D-rich foods to promote bone health.

Generally, when崴脚 (sprained foot) occurs and there is a specific painful spot on the instep upon palpation, it is mainly caused by reasons such as muscle strain, ligament injury, hematoma, joint dislocation, or fracture. If discomfort occurs, seek timely medical attention and follow the guidance of a physician for treatments such as general therapy or medication therapy. A detailed analysis is as follows:

1. Muscle Strain

When the foot suddenly twists, the muscles on the instep endure stress beyond their normal capacity, causing partial or complete rupture of muscle fibers, resulting in localized pain and swelling. Applying heat compresses and massage can help promote blood circulation and accelerate recovery.

2. Ligament Injury

During a foot sprain, ligaments connecting the bones may also be stretched or torn, especially the lateral ligaments. Ligament injuries can lead to localized pain, swelling, and reduced joint stability. Rehabilitation exercises to strengthen surrounding muscles can help restore joint stability.

3. Hematoma

Following a崴脚 (sprained foot), local blood vessels may rupture, leading to hematoma formation, which compresses surrounding tissues and causes pain. Symptoms can be relieved through rest, cold compresses, and compression bandaging.

4. Joint Dislocation

In cases of joint dislocation, the normal anatomical relationship of the joint changes, causing pain, swelling, and joint deformity. Prompt medical attention is required for joint reduction, followed by immobilization and rehabilitation training.

5. Fracture

With a fracture, the integrity or continuity of the bone is disrupted, causing severe pain, swelling, and deformity. Symptoms may include local deformity and bone friction sounds. Under the guidance of a qualified physician, medications such as diclofenac sodium sustained-release tablets, Huoxue Zhitong capsules, and Da Qilie capsules may be used for treatment.

Maintaining a balanced diet in daily life and consuming foods rich in calcium, vitamin D, and other nutrients can help promote bone health.
