Heel cramp pain may be caused by the following reasons: 1, lumbar disc herniation compressing the sciatic nerve, resulting in radioactive pain symptoms in the sciatic nerve innervation area, which can be launched to the legs as well as pain at the heel, and patients are mostly accompanied by pain in the lower back. 2, if the usual activity is relatively low, strenuous activity or long distance walking within a short period of time, resulting in muscle spasm at the heel, leading to 3, middle-aged and elderly patients due to calcium deficiency leading to osteoporosis or osteophytes, the formation of bone spurs compressing the surrounding tissue fascia, causing local pain symptoms. 4, long-term chronic strain on the heel leading to Achilles tendinitis or plantar fasciitis, will also cause pain in the heel. 5, high falls and other reasons leading to fractures of the heel bone, will also cause obvious symptoms of cramp-like pain in the heel.
