I'm only 20 and my fiancé just picked me up from a friends house because I fell asleep there. When I got in the car I smoked a cigarette and as soon as I did I felt some indigestion so I got freaked out and I have an app that measures my pulse and blood pressure and I've never had a problem with my blood pressure in the past and it's always been normal if not a little on the low side but nothing the doctors were worried about and this app told me my blood pressure was 170/105 and I started to go into a panic because I did the dreaded G and it was telling me to go straight to the hospital but every time I've rechecked it its a little lower but still high. My anxiety is through the roof right now and I'm so scared. Should I go to the ER?
