If the blisters are large or the walls are loose, it is recommended to use a sterile needle to pick the blisters and then apply boric acid solution and Levanox solution as a wet compress, and apply topical Bactrim to prevent infection. Thirdly, local irradiation of red and blue light and helium-neon laser can help absorb the lesions and reduce pain. Fourthly, local closure treatment can be performed to treat posterior neuralgia.
