Which department should I visit for unilateral lower limb swelling?

In general, for unilateral lower limb swelling, patients may seek consultation from dermatology, orthopedics, endocrinology, nephrology, or cardiovascular surgery. Specific details are as follows:

1. Dermatology: Dermatology primarily focuses on skin-related conditions. Skin infections, eczema, herpes, and other factors may cause localized swelling, often accompanied by additional skin symptoms such as erythema or itching, which could lead to the aforementioned condition.

2. Orthopedics: Orthopedics specializes in disorders related to bones and joints. Unilateral lower limb swelling may be associated with fractures, bone tumors, arthritis, soft tissue injuries, or other skeletal diseases.

3. Endocrinology: Endocrinology deals with disorders of the endocrine system. Certain endocrine diseases, such as hypothyroidism or hyperthyroidism, may lead to unilateral lower limb swelling.

4. Nephrology: Nephrology focuses on kidney-related diseases. Kidney problems may cause fluid retention, leading to lower extremity edema and the symptoms described above, such as glomerulonephritis, nephrotic syndrome, or renal failure.

5. Cardiovascular Surgery: Cardiovascular surgery involves the treatment of heart and vascular diseases. Conditions such as deep vein thrombosis (DVT) or venous thromboembolism may result in the aforementioned swelling, typically related to vascular obstruction or circulatory problems.

Patients are advised to seek timely medical attention when experiencing discomfort and to receive standardized treatment under a physician's guidance, which can facilitate recovery.
