So I was at work yesterday and my shift was over so I sat down and started using phone but all of sudden I felt tingling in my throat like something is coming out and then soon i had rapid heartbeat or palpitations but no other symptoms just a little rapid heart rate which also increases when I walk or walk up stairs so I ate nothing and slept in the morning my heart palpitations were not much but I was feeling like I was not hungry anymore and extreme fatigue so I drank saunf ajawain milk after which I became completely fine what was that ?
