Am i okay?

I used to vape heavy and been smoking weed since 14 but I stopped for awhile after greening. Now I'm back on it my chest seems to hurt when I smoke pot? Is it just my body not being used to it? Whenever I workout and my chest pumps hard it doesnt hurt tho. Should I be worried, I'm 17 now I vaped for like 2years and finally off because of the chest pains too. But ya When I smoke weed my chest hurts is my body just reacting that way because its not used to it or should I get checked.
