Foot pain should be alert to joint inflammatory diseases, lumbar spine diseases, acute and chronic injuries and other lesions. 1. Joint inflammatory diseases: such as rheumatoid arthritis, osteoarthritis, gouty arthritis, etc., the inflammation of the joints will cause damage to the joints and surrounding tissues, thus causing foot pain. 2. Lumbar spine diseases: such as lumbar disc herniation, lumbar spinal stenosis, etc., these lesions will cause compression of the nerve root, thus causing radiating pain in the legs and feet, accompanied by numbness and weakness and other symptoms. 3. Acute and chronic inflammatory injuries: Acute trauma to the foot, such as crush injuries, bruises, etc., if there are soft tissue and bone injuries can also cause pain. Chronic injuries, such as plantar fasciitis and Achilles tendonitis, can also cause foot pain. Foot pain can also be caused by other things, such as onychomycosis, bunions and plantar fasciitis. If the pain is severe, or the condition is recurring, or accompanied by numbness and weakness, you should go to the hospital in time to further identify the cause of the disease, and then targeted treatment.
