There are many reasons why climbing stairs and thighs are particularly acidic, and the common ones are myofibrositis, lumbar disc herniation, and chronic strain injury.
1. Myofibrositis: a series of syndromes caused by edema, exudation and fibrous degeneration of myofascial or muscle tissues due to cold, injury, etc. It can be manifested as pain, soreness and muscle tension when it occurs in the lumbar back and thighs, and it can be accompanied by postural abnormality and dysfunction.
2. Lumbar intervertebral disc herniation: Due to degenerative changes of lumbar intervertebral discs, the nucleus pulposus prolapses or protrudes out of the annulus fibrosus, which compresses the surrounding nerve tissues, leading to lumbar pain, weakness of the lower limbs and other symptoms. Symptoms are aggravated when climbing stairs, resulting in particularly sore and swollen thighs.
3. Chronic strain injury: due to long-term overload activities or poor posture leading to chronic muscle injury, climbing stairs, lactic acid can also cause a large number of gathering thigh pain symptoms.
There may be other reasons why thighs are particularly sore when climbing stairs. If the symptoms persist and are accompanied by pain, it is recommended that you consult a doctor in a timely manner to clarify the cause of the problem and then actively standardize the treatment.
