Patients with neuralgia can be treated with B vitamins, such as vitamin B1, vitamin B6, vitamin B12, etc. B vitamins have the function of nourishing peripheral nerves and promoting recovery of peripheral nerves. However, for patients with neuralgia, it is recommended to find the cause of the neuralgia, such as compression, trauma, tumor, inflammation and so on. If the neuralgia is caused by compression, the pain may be relieved naturally after the compression is removed; if it is caused by tumor occupancy, surgery is needed to remove it; if it is caused by inflammation, antiviral or anti-infection treatment can be considered to eliminate the inflammation.
