Sensitivity to temperature is a skin sense that is related to the human need to maintain internal temperature balance or thermal homeostasis. Temperature sensitivity is important in protecting one's self from intense temperature that may cause damage to the body.
Just to be clear, There is a difference between pain and sensitivity. Pain is when your teeth hurt, like when you fall down and your knee/elbow hurt. Sensitive is a tingling sensation. It is present only when there is exposure to cold, hot, sour or initial disease. You might be facing sensitivity issues here like the others have mentioned.
