hello everyone. sorry to bother. I had a question. so today I brought some bags inside from the grocery store. and I noticed I was coughing and when I took a deep breath i felt and heard a crackling kinda thing. I relaxed and moved around after a bit to try and see if it would happen again. and it did. I had an echo done 4 months ago in February 23rd and. my electrophsyilogist said my heart was fine. and my heart wasn't weak. should I be worried? I'm going on 20 years old and I am tired of worrying. and any advice on my compulsions? cause I keep trying to exercise and take deep breaths to see if there is a sound.
