allergic reactions
"I was given Benadryl at the hospital for an allergic reaction. It instantly shot my heart rate up to 217 bpm and instantly my mouth got dry I couldn't swallow my chest felt hot like an elephant was sitting on it and I got really cold. It put me into shock my body wouldn't stop shaking, I could breath.  It was so scary I thought I was dead thanks to the doctors quick response he saved me but it almost killed me. "
