· Skin changes: The skin is the largest organ of the body which makes it to be a window into our overall health. Jaundice is a symptom that could suggest a possible infection. Regardless of the cause of the sign, you should check it out. Another cause for concern is changes in moles and you should speak with the doctor if a mole: is asymmetrical, or has jagged edges, has funny or irregular borders, changes color or get darker, is large or growing.
· Persistent coughing: Infections and viruses can eventually blow themselves out so when you have a cough for a few weeks, it is probably that you have picked a bug. Chronic coughing is a different game altogether. It is more dangerous when it causes you to become breathless or makes your throat so sore that you have difficulty swallowing.
