Thigh swelling and soreness are usually caused by lumbar disc herniation, venous embolism, fasciitis or excessive exercise.
1. Herniated lumbar disc: when the herniated lumbar disc compresses the nerves and stimulates the innervated muscles of the lower limbs, symptoms such as radiating pain, weakness and numbness in the lower limbs may occur, causing thigh pain.
2. Venous embolism: it is easy to occur in the elderly and may be a complication of surgery such as arthroplasty. If the embolism occurs in the deep femoral vein, etc., it may cause pain in the thighs and swelling of the lower limbs.
3. Fasciitis: Fasciitis in the thigh area will stimulate the peripheral nerve tissues and cause different degrees of pain. Soft tissues will ooze faster after being affected by inflammation. Some of the exudate that cannot be absorbed in time will accumulate in the affected area, leading to localized swelling.
4. Excessive exercise: mainly due to too long or too much exercise, resulting in excessive muscle contraction of the thighs, causing an increase in local lactic acid metabolites, which triggers soreness in the thigh muscles.
If you have symptoms, you should go to the hospital in time to determine the cause of the condition under the diagnosis of the doctor and carry out targeted treatment.
