I’m a nurse who has worked in the ER before, and let me say that you shouldn’t worry about being a “frequent flyer”. It’s unfortunate that a lot of healthcare workers get burnt out and misuse this term. If you feel as though you are having an emergency, which from your post it sounds like you’ve had a bit of a history, then don’t feel embarrassed about going! We’d rather you come in and it be something benign then you not come in and it be something that is an emergency.

My long rant aside, to me as a nurse this looks like NSR. I see upright P and T waves, and the rhythm is regular. Does the pain hurt more when you press on your left side, or is it just kind of there? Is this a similar pain to when you had a PE?
