Tightness pulsing feeling, any one relate?

Hi again...I have a question for y'all.

Lately I've been feeling like pulsing tightness on my left side chest of course I freak out thinking a heart attack. It goes away and comes back with sharp pinching pain/sensations. Gets also tinginli. The pain I feel on the left side is described as if you try to move your breast and squeeze idk how to explain. Idk I sometimes feel it on the left side. Praying helps a lot but I was just wondering if y'all feel this also. Burping helps thank you in advance I appreciate as all of y'all this community is great God bless y'all
