Hello @siddlebittle - I combined your most recent update with your original post, https://connect.mayoclinic.org/discussion/palpitation-and-chest-pain/, and combined it with the Bones, Joints & Muscles and Heart Rhythm support groups.

@siddlebittle, is there anything in particular that helps the sensations go away? The emergency room ran quite a bit of tests, have you considered asking a referral to a specialist?
