Have flu for 5 days. Still having problems breathing, no appetite, constant throwing up, now sharp pain in lower abdomen when coughing, fevers no energy?

Visit Urgent Care/ER. Hello Stephen I am sorry that you are feeling ill. If you are having high fevers, difficulty breathing, and constantly throwing up I would advise a visiting a Urgent Care facility or ER as soon as possible. Without a set of vitals I don't know how bad your flu is, so I would advise medical attention.
