16f: weeks ago, i had chest pressure. i went to er and they suspected it was stress/anxiety. it went away. but i still hear rumbling in my chest and let gas out. my bpm goes to 160 sometimes and hurts. legs tingling and heavy head for past 2 days?

It may be more than one thing. One possibilty is reflux which can radiate and cause chest discomfort; another is gall bladder disease. Regardless, with either one of these problems, it could increase her anxiety which can increase the perception of pain which could increase the anxiety and so forth. You need to check with your medical doctor about these or other possibilities.

An EKG 12 lead may provide additional information. Monitor BP and consider a COVID 19 screening test. If you have been sick in the last month, MIS C should be considered. A full evaluation is recommended.
