Hello sir/ma, I feel very cold inside, when everyone in the same complains its hot. When the cold feel increases i get pains on both sides of my chest. I no longer use the airconditioner nor expose myself to direct cold cos this increases the pain. Sometimes i feel myself sweating outwardly even though i still have this internal cold. I am a 31 year old male, and this situation keeps getting worst. I am scared really. What can be the cause.
