I feel of excessive sweating for the last 1 year or so.  Even while doing a minor/medium physical activity,  my vest is fully soaked.  Sometime even while sleeping at midnight in AC room I feel sweating around my neck or upper body areas  especially which face downwards towards the bedding.  Stress ECO was done last year, everything normal, Cholesterol level - total 174,LDL /VLDL- 109/17,HDL - 48 blood sugar fasting 100,BP 85/125. What could be possible causes. I am thinking of getting CT Coronary Angiography to rule out possible blockage of arteries. Pl suggest
