Blood pressure normal in 60's and is currently in high 40's and i am tingling all over?

On may may into work i was tingling all over my body like your foot does when it falls asleep. I Guide Zip lines and during the entire time i felt fine. On my way home after not being real active for 30min the tingling came back but real bad. I could barely move my joints so i pulled over and got some Gatorade and crackers, hung out for over an hr and my hear rate was in the 40's from 44bpm to 48bpm. I felt that tingling all over my body and parts of my face twitched. I puked up the Gatorade, i felt like i was about to pass out, and i was really warm but it was a cool wet day. Some one told me i just needed to get the blood flowing again so i jumped off a 5t fall to get the adrenalin going and i was able to make it home fairly well. Now that i am home i am just starting to feel the tingling. What is wrong with me?
