Intercostal neuralgia generally refers to intercostal neuralgia, which is mainly related to trauma, infection or other diseases. 1. Trauma: If you are hit by external force, it may lead to local tissue damage, and therefore induce intercostal neuralgia. 2. Infection: If infected with herpes zoster virus, Mycobacterium tuberculosis or other pathogens, they may lurk in the ganglion, thus inducing intercostal neuralgia. 3. Other diseases: Clinical tumors, peripheral neuritis and other diseases may lead to intercostal nerve tissue disorders, so intercostal neuralgia symptoms. If intercostal neuralgia occurs, it is necessary to seek medical examination and treatment in time to avoid complications in the later stage.
