Introduction
Aching, fatigue, and swelling in the lower legs and feet may be caused by physiological factors or pathological conditions such as piriformis syndrome, lumbar disc herniation, etc. It is necessary to visit a hospital for an accurate diagnosis and to relieve discomfort through general treatments or medications. Additionally, conditions such as kidney disease, right heart failure, and lower limb arterial sclerosis may also cause these symptoms. Patients are advised to seek medical evaluation at a hospital to determine the underlying cause.
Feeling of soreness, fatigue, and swelling in the lower leg and feet may be due to physiological factors or pathological conditions such as piriformis syndrome, lumbar disc herniation, etc. It is necessary to visit a hospital for an accurate diagnosis, and symptoms can be relieved through general treatments or medications. Specific analyses are as follows:
I. Physiological Factors
Swelling in the lower legs and feet commonly occurs after prolonged standing or sitting, during which the lower limb muscles remain inactive and venous blood flow becomes impaired. Symptoms usually improve with appropriate physical activity.
II. Pathological Factors
1. Piriformis Syndrome
This condition primarily results from stretching of the piriformis muscle, leading to muscle edema and hypertrophy. The affected muscle may irritate and compress the sciatic nerve at the site of the piriformis, causing soreness and swelling in the leg and foot. Patients may be treated under medical guidance with medications such as Huoxue Huayu Capsules, diclofenac sodium tablets, or loxoprofen sodium tablets.
2. Lumbar Disc Herniation
Lumbar disc herniation can compress spinal nerve roots or the spinal cord, resulting in abnormal sensation and motor function in areas of the lower limbs innervated by these nerves, causing patients to experience swelling, pain, and numbness in the feet and lower legs. It is recommended that patients undergo endoscopic discectomy under the guidance of a physician. If lumbar instability is present, open interbody fusion surgery may also be required.
In addition, other conditions such as lower extremity varicose veins, renal edema, and peripheral arterial disease may also cause the above symptoms. Patients are advised to seek medical evaluation at a hospital to determine the exact cause.
