Hi. i am currently 23 years old and i always feel a heat sensation around my face and neck regardless whether it is cold or hot. If i watch tv or do unimportant actvities,i am not bothered but it is still there. However, once i start studying and need to concentrate, i always feel this irritaing heat feeling around face and neck and it is impossible to achieve anything. Please help me if anyone has sugestions and what tests should i take, My thyroid, glucose and pressure levels are normal.
