Upper back/neck strain caused heart palpitations.
I recently strained my upper back from over working on my laptop (staring down too long) and then over stretching. I felt like I pulled something in my upper spine, and ever since have had some heart palpitations (normally when bending over or looking down too long). My back and neck are not 100% yet, but they have improved, and so have the heart palpitations for the most part (get them a few times a day now if I bend or lay in a weird position). Any idea why this happened from my strain of my upper spine and lower cervical? Any advice? I am 28 year old male (6'6 tall), that is very athletic, just for some context.
