Sorry for the long post, but here's a little background.
I'm a moderately healthy 21M who has had very minor anxiety throughout life, I would say a very normal amount of anxiety, and have only had maybe 3 panic attacks my whole life, 2 of which woke me out of my sleep. It's surprising because anxiety disorders run on both sides of my family, so I'm very grateful this isn't one of my struggles.

However, recently I've been having some stomach issues and I've been dragging my feet about seeing a doctor about them. So it's been bugging me all week and I finally decided to make a doctors appointment when I finally got home, because my stomach was bothering me, but during my travels I noticed my heart rate was pretty high, between 75-85 bpm, which is higher than normal (my average resting bpm is between 55-65.) But I started getting a bit nauseous (which I attributed to the stomach issues) and kinda brushed it off and decided to just go home. Well, I didn't much feel like driving so I just got a ride from someone, and at this point my bpm was well over 100, which I found very concerning. So when I got home I planned to have my wife bring me to the ER anyway just to be safe, however, about 5 miles from my house, very suddenly my heart shot up to nearly 150 bpm (I measured, so it wasn't a guess), and my chest started hurting a little, so I started panicking a little bit, when suddenly my arms and legs started feeling really cold, tingly and pretty weak, so I ended up calling 911 and having an ambulance meet us halfway because I thought I was having a heart attack (heart disease runs in the family, brother had his first, albeit minor, heart attack around 25) but the EMT's said my rhythm looked okay, and it likely wasn't a heart attack, but my bpm and bp were by the time they measured were 139 and 158/84 respectively, so we go to the hospital anyway, and they give me the all clear, and refer me to a local Dr. Office, which I'll be seeing in a few days time.

*I should note they said it was probably just because the panic attacked altered my breathing and caused the tingly limbs, but I felt like I was breathing normally at the time, in fact I was making a conscious effort to take slow deep breaths so I wouldn't hyperventilate, but the attack happened regardless.

I'm still a bit concerned about the whole ordeal, because that's very atypical for me, and I've never had cold/tingly limbs during an attack, has anyone else experienced these symptoms during a panic attack before?
