Anyone else had this before?

Okay so I smoked a pen cartridges called green box (I usually smoke stiiizy pens) and I noticed after that I couldn’t breathe well and my lungs feel so stuffed like I can’t breathe and every time I breathe I feel congested and I make wheezing noises. I stopped smoking, It’s been days but it’s still the same. Anyone know what it is? What should I do?
