Patients with diabetic neuropathy can be treated by controlling blood sugar, using nerve-nourishing drugs and painkillers. 1. Control blood sugar: If the human body is in a constant state of high blood sugar, the nerve fibers in its limbs will be damaged, which in turn will cause neuralgia. Therefore, diabetic patients should keep their blood sugar within normal range as much as possible to prevent or improve the symptoms of neuralgia. 2. Use nerve-nourishing drugs: patients with diabetic neuropathy can use B vitamins, methylcobalamin, lipoic acid capsules and so on as prescribed by the doctor. 3. Use of painkillers: patients with diabetic neuropathy can use aspirin, ibuprofen and other painkillers to relieve pain when severe nerve pain occurs. When diabetic neuropathy occurs, it is recommended that patients go to a regular hospital, cooperate with the doctor to complete the relevant examinations, and actively deal with it.
