Scared of 'Dry Drowning" - anxiety pretty bad right now

[MarieLily]

I found this account that I've had here and I believe I posted last year. I get awful health anxiety during the summer and sharing with people puts me at ease.
Something terrible happened in my city related to what I learned is "dry drowning" and I didn't think it will remain on my mind, but it surfaced now.

I was eating and drinking right now, and after I drank my glass few seconds later I got this need to cough. I coughed and there was sudden pain over my left side of the chest and my left arm. I freaked out and first thought heart attack (I am a 23 year old female) and then few seconds later the "dry drowning" came back to me.
I am currently scared some of the coke went into my lungs and that I will "drown" from it because I read on WebMD that even a small amount of water can cause "dry drowning".

Does this sound plausible to you guys or do I sound ridiculous? I don't want to call the ER and tell them I think I might drown from a cup of coke from KFC but I got a full blown anxiety attack over this right now

Well did you choke on the drink? If something entered your airway, you would have felt pain in your respiratory system, namely your trachea and bronchus, since this is coke we are talking about.
I don't know much about dry drowning, but this is what Google said regarding dry drowning in a pool--
"Swallowed water goes into the esophagus and down through the digestive tract. ... ASPIRATION is when the water goes into the trachea and down into the lungs. In this case, the patient in question will have an episode of distress after they come out (or are pulled out) of the water. You will see it and you will KNOW they are not OK."
In other words, you would have known if you were experiencing something way more serious. Hope this helps.
