Uncomfortable Air Bubble Beneath My Ribs

i gotta be honest i have no idea if any of you are gonna know what I'm talking about but. back in october (2021) i was in a one-act competition play for my high-school. we were supposed to breathe funny, rasp, wheeze. while doing so, i felt something... shift...? and i haven't been the same since. it feels like an air bubble beneath my ribs. it is very uncomfortable. it is only on the left side, so my ribs feel uneven. sometimes i forget it's there, but other times it's unbearably uncomfortable. i gained a new party trick that day- i can pop my ribs! i could feel something wasn't right, so i had a few friends put their hands on my waist and i would "shift" things back. some people say they can feel the shift, some don't. i feel it. i REALLY feel it. i've had multiple x-rays, all came back normal. but sometimes, this space has SO much air in it, you can hear it. when it shoves itself past my intestines or i pop my ribs, it makes a sound. sometimes i record it and send it to my friends, but they don't find it nearly as funny as i do. anyway, i am very tired of being dismissed by doctors. anyway, thoughts? tips? questions? validation-?
