Hello @peach0201, I'd like to add my welcome to @jc76 and @peaches1234. Mayo Clinic has a great resource to help plan for trips to all of their locations: https://www.mayoclinic.org/patient-visitor-guide. You can click through based on where you will be visiting and the various resources like travel, lodging, things to do and transportation will be listed for your location.

@peach0201, have you seen a local cardiologist or asked for a referral for one? You mentioned your visit(s) to the ER, but that is a hard way to get diagnosed as they are treating the acute issues vs. long-term diagnosis. You mentioned they can get worse when you lay down to sleep, is this an every evening issue?
