There are also a lot of neurotrophic injections, such as methylcobalamin injection, vitamin B12 injection and vitamin B1 injection. However, the selection of injections should be made under the guidance of doctors, and special attention should be paid to the combined use of these injections, such as the combined use of vitamin B1 and vitamin B12 injection, which still has a relatively certain effect on nerve nutrition. Of course, in addition to the use of neurotrophic agents, we should also consider the control of the patient’s symptoms and the treatment of the cause of the disease, which are very necessary treatment measures, as well as regular neurology review. Since nerve damage is irreversible after a long period of time, it is important to seek medical attention in a timely manner to remove the primary cause of the nerve damage, remove the causative factors, and select acupuncture and physiotherapy for symptomatic treatment.
