Thanks for answering my questions,I really appreciate that.
Now looking at your age and gender there is a possibility that you are having cold sweats most likely due to menopausal symptoms,you can ask your physician to check for serum fsh and lh.
Other possibility could be thyroid
problems as that may also cause similar symptoms like sweating in cold room,as hyperthyroidism
increases the basal metabolic rate and leads to these symptoms.Ask your physician to do thyroid stimulating hormone to rule this possibility.
There is also data suggesting that quinine sulfate can also symptoms like yours so you should also talk to physician about this possibility,if required switch to other medication.One of the possibility at your age could be arrhythmia as you do have history of high blood pressure
and that does present with similar symptoms,but as you mentioned ekg was normal so that is low in out list.Still if possible ask your physician to do holter monitor.
