Shingles can cause swollen lymph nodes. Herpes zoster is a skin disease caused by the varicella-zoster virus. After being infected by the virus, the body will try to remove the virus by all means, mobilizing the lymphocytes in the lymph nodes, allowing them to proliferate and become active to kill the virus, which in turn will lead to swollen lymph nodes, so it is very normal for herpes zoster to cause swollen lymph nodes, and the degree of swollen lymph nodes in the face and neck of herpes zoster is often higher than in other This is a physiological stress reaction. After getting shingles, you can take oral acyclovir and topical fusidic acid cream, as well as oral thymidine and pidomod to improve immunity, and oral vitamin B1 and vitamin B12 to repair the nerves.
