Talk to General Physician on Chest Tightness

its been a long time since im facing this issue but it has been aggravated since the past 2-3 weeks. Im facing very tight chest and i feel like as if i need to yawn to breath resulting in excess yawning. In addition I sometimes feel pain on my chest bone too. It's a feeling of something stuck in the centre of my chest. Please any suggestion or help would be appreciated. Also I cant risk going to the Hospital because of this Corona pandemic.

I am 19 years old, my height is 5'8, Weight 98 Kgs, and no medical history.
