12 Common Symptoms Of The Flu

11. Chest Pain

Some conditions caused by the flu may become more complicated. While a number of symptoms clear up on their own or with home remedies, upper and lower respiratory tract infections may lead to more serious conditions. One such complication that the flu may lead to is myocarditis, which is an inflammation in the middle layer of the heart’s wall. This may cause symptoms typical of the flu such as fever and fatigue, but may also have more serious consequences, such as chest pain, arrhythmia, heart attack, or a stroke.
