Foot drop is an abnormality in which the forefoot “drops”. It is caused due to weakness, irritation or damage to the common fibular nerve including the sciatic nerve, or paralysis of the muscles in the anterior portion of the lower leg. It is usually a symptom of a greater problem, not a disease in itself.
The most common cause of foot drop is compression of the peroneal nerve which controls the muscles involved in lifting the foot.
There are multiple ways of helping to cure, but stimulating blood flow to the area may help alleviate the symptoms.
