When is a cough “just” a cough, or a headache a symptom to be concerned about? Listed are signs and symptoms that could indicate a serious health condition, and you should see a doctor if you experience any symptoms of concern. Sometimes, a symptom in one part of the body may be a sign of a problem in another part of the body. Moreover, unrelated symptoms that might be minor on their own could be warning signs of a more serious medical disease or condition. Listen to your body, note all symptoms, and share them in detail with your doctor.
