What is the reason for men’s cold feet, men’s feet are cold for two main reasons: first, neurological reasons. Because of herniated lumbar discs, sciatic neuropathy resulting in the inability to innervate the nerves of the foot, there are cold feet, but the feet are not cold. Second, vascular causes. Blood vessels do not work, blood can not pass, heat can not be transmitted to the feet, so some people will feel cold feet. If there are cold feet, it is important to distinguish which cause is caused by, if it is a neurological cause, nourishing the nerves can be. If it is an arterial problem, it depends on what the cause is. Cold feet caused by arterial disease, such as atherosclerosis, requires medication and intervention to open the blood vessels. If it is vasculitis, in the acute phase, the main focus is on drugs. If it is in the chronic stage, the specific choice depends on the preoperative examination. If a CTA examination is done and the calf is in good condition, it can be treated by bypass and also by intervention. The specific cause depends on the onset of the disease, and different treatment modalities are adopted for different causes.
