Peripheral neuralgia may be caused by trauma, inflammation, tumor, diabetes, primary, etc. It needs to be treated with medication, physical therapy, surgery, etc. for the cause. 1. Trauma: puncture wounds, contusion wounds, crush wounds and other traumatic injuries lead to mechanical damage to the peripheral nerves, resulting in neuralgia. Surgical disinfection and debridement, hemostatic bandage or even surgery are needed to repair the trauma, and medicines such as methylcobalamin, epothilone, vitamin B, lipoic acid and other drugs should be applied to nourish the nerves. 2. Inflammation: Inflammatory lesions occur in the area where peripheral nerves pass through, which involve the nerves and lead to neuroinflammatory lesions and pain.

Tumor: pain occurs when peripheral nerves are compressed and invaded by malignant tumors, which can be treated by surgical resection of the tumor and radiotherapy. 4. Diabetes mellitus: long-term diabetes mellitus leads to peripheral neuropathy, resulting in neuralgia. You can take metformin, selegiline and other drugs or subcutaneous injection of insulin to lower glucose, and apply methylcobalamin, epothilone, vitamin B, lipoic acid and other drugs to nourish the nerves. At the same time, it can be combined with acupuncture, physiotherapy and other treatments. 5.
