Patients with HFMD are generally allowed to eat fish and shrimp, but they should be careful that the fish and shrimp do not cause adverse reactions to the body, which may cause allergies as well as aggravate sore throat. In HFMD, there are herpes and even ulcers in the isthmus of the throat, which can cause sore throat and worsen sore throat when swallowing. Fish has spines that may stick to the throat, and shrimp also has hard shells that may aggravate the sore throat more than other foods when swallowed. If the sore throat is aggravated, it is not particularly recommended to eat, you can eat more easily digestible liquid food. Fish and shrimp can be eaten after the symptoms of sore throat have subsided. Fish and shrimp are proteins that are different from the human body and may cause allergies, but in cases where fish and shrimp do not normally cause allergies, they generally do not cause allergies when it comes to HFMD.
