Hi everyone well the other day was very very cold, and as i was shivering in the cold with a semi thin jacket, i was so cold I was shivering like crazy and i felt like i was going to have a heart attack or something, i had problems catching my breath, there seemed to be a tightness in my chest and this seems to happen in extreme cold when i am not bundled up too much (temps were 30 degrees), when i warmed up a felt much much better but it took about 15 min. It seems this has happened since i was about 21, when i had mono i have never been the same when it comes to the cold. Also i have slightly high blood pressure that ranges from 129/140-68/80. I know its not severely high but high for my age nonetheless. Any insight would be very appreciated, and by the way I take 5mg norvasc, 5mg paxil not sure if this would contribute to that.
