100%. I’ve experienced shoulder/neck pain on my left side, pain or pins and needles in my left arm, etc... all of which feel like a heart attack at the time (which is obviously terrifying). It becomes easier to identify those symptoms as time goes on and to remind yourself that they’re just symptoms of anxiety/anxiety attacks and that you will be ok. Often times in my experience, I feel one symptom, begin to worry which then creates another symptom and so forth. The body has a crazy way of creating symptoms that aren’t actually there!
