I've been dealing with some really uncomfortable symptoms and I'm getting kinda worried. My stomach has been bothering me a lot with gastritis, and Im burping a lot too. I feel this pain on the left side of my abdomen and this heaviness in the middle of my chest, especially when I try to sleep. There's this weird tight feeling in my throat and one side of my nose swells up. Whenever I take a deep breath, my ear kinda closes off which feels strange. When Im trying to sleep, sometimes my heart starts racing and I find it hard to breathe. My head feels heavy throughout the day which is really annoying. I havent lost any weight, Im not losing my appetite, and I dont smoke or drinkI'm vegetarian too. Does this all sound serious? Any idea what might be going on?

it is due to sinusitis or deviated nasal septum. take steam inhalation
