Hi, im worried i have some kind of chest infection and would please like advice. it feels more serious than i initially thought, but since there are no open doctors i am wondering if i should go to emergency room?

Depends on details: The chest is between the neck and the abdomen, excluding the shoulders and arms. There are a lot of places in the "chest" area that can get infected. With no details, general reasons to go to an ER are to get care for serious, urgent problems that cannot wait for a non-emergency appointment. Reasons include difficulty breathing, chest pain, high fever, altered mental status, serious bleeding, etc.
