7 BODY SIGNALS YOU SHOULD NOTIGNORE

Fever does not go away.
A fever usually means your body is fighting an infection. A low-grade (38oC or 100.4oF) fever that persists (for more than a week) may indicate a more serious illness, such as a urinary tract infection, tuberculosis, or lymphoma.
Shortness of breath.
Shortness of breath or stuffy nose after exercise is considered normal. However, if you feel relaxed and fighting for air, this may be a cause for concern. If you experience wheezing or shortness of breath while lying down, it’s time to see a doctor. Chronic obstructive pulmonary disease, chronic bronchitis, asthma, heart disease, anxiety, panic attacks, blood clots in the lungs (pulmonary embolism), pulmonary fibrosis, and pulmonary hypertension are the culprits.
