After nerve injury, especially brachial plexus nerve injury, the affected limb cannot move, which brings a heavy burden to the patient’s work and heart. Rapidly restoring the function of the affected limb is a problem that patients urgently need to solve. Due to the lack of understanding of the law of nerve injury recovery, as well as the current existence of subspecialties too fine, the lack of mutual understanding between disciplines to understand each other and other reasons, patients need to choose the right treatment method, rather than blindly surgery or the pursuit of expensive drug treatment, which affects your efficacy and brings you a heavy burden financially, and even brings a negative impact. How to diagnose and treat nerve injury? We put forward a few suggestions for your choice: 1, first of all, to clarify the site and degree of nerve injury: according to the symptoms that appear after nerve injury to determine the site and degree of nerve injury, you need a doctor with good knowledge of neuroanatomy and extensive clinical experience to choose the right treatment for you. 2, the choice of treatment: from our clinical analysis of treating a large number of patients with peripheral nerve injury, most are partial nerve injuries such as strains, lacerations, etc., and a small number are complete transection injuries such as knife cuts. If the knife cut injury surgical anastomosis of the nerve is the first choice, if the partial injury, rehabilitation is the first choice. 3, nerve recovery: nerve recovery is a very slow process, the degree of nerve damage, recovery time is different, the longest time to recover from nerve damage 1-2 years, short 1-2 months, usually 3-6 months. 4, rehabilitation treatment: rehabilitation training and NMR-type neuromuscular electrical stimulation treatment is very effective, need to be based on the location of the patient’s nerve injury, nerve involvement and muscle parts of the rehabilitation treatment. To increase the blood circulation of damaged nerves and provide nutrition for nerve regeneration. 5, overcome the ambiguous understanding, in medical diagnosis and treatment is not the more expensive examination or treatment is better, but to choose the most effective or correct treatment method suitable for such conditions. Many patients do not understand the law of nerve damage and recovery, and blindly use expensive drugs and inappropriate treatment, resulting in a heavy financial burden and even lifelong disability.
