So last night i had to call the ambulance again.... hr went to 170 when i took my bp it was 170 over 105 with a 135 heart rate my body was shaking like i was freezing cold calmed down after about 30 minutes to an hour i am not really sure what to do during these episodes as they are fairly new to me i had 1 a week for the passed 3 weeks i feel awful the next day as well.... and when it happens it feels like doom ...i know it sounds silly but its the worse feeling in the world can any 1 help me with this ? has any 1 ever had this happen 2 them ? and if so how do you cope with it ? doctors are looking into pheo and etc until then i am not sure what to do i cant keep calling the ambulance =/
