Left leg pain that lasts for a long time may be caused by various reasons. The following are some common possible causes:
1. Overexertion: Prolonged heavy physical labor or overuse of the left leg may cause muscle strain, presenting as pain and swelling.
2. Muscle strain or soft tissue injury: Overstretching or external impact on the muscles of the left leg may lead to muscle tissue rupture or damage to subcutaneous soft tissues, causing pain.
3. Bone fracture: Direct or indirect trauma to the left leg may cause bone tissue to break. Movement can irritate the fractured tissue, resulting in pain.
4. Nervous system disorders: Conditions such as sciatica, lumbar disc herniation, or spinal cord lesions can affect nerve conduction and cause pain in the lower limbs.
5. Vascular diseases: For example, arteriosclerosis obliterans or deep vein thrombosis, which affect blood circulation and can lead to ischemic leg pain.
6. Metabolic diseases: Such as peripheral neuropathy caused by diabetes, or muscle weakness or pain resulting from thyroid dysfunction.
If left leg pain lasts for a long time or is severe, immediate medical examination at a hospital is necessary.
