Chest problem. I think in bmi it's high.

I don't know what happen but I am having a feeling that something got stuck in my chest and this sensation is weird and it's getting scary now. I don't have oxygen problem, I don't have any pain. I mostly sleep on my stomach side and after sleep I don't get any sensation but after eating food i get that mostly and in this pandemic time I get worried easily that what if I am having covid but I check so many times I don't have any symptoms of covid. then why it's happening and what's going on I don't know. can it be because of my obesity because in 2 years I became fat not that much fatty but yes my weight is more than 82 kg and I think in BMI it's high. it's like when someone cry a lot and after that you feel heaviness in chest, this is same feeling without cry but I don't feel this in my whole chest I feel this in my upper centre part of the chest, it's like it's in food pipe but I don't know so I need some guidance what should I do to get rid of this sensation.
