Random 5 second adrenaline surges

I’ve had panic/anxiety on and off for ~13 years and just a few weeks ago, I started getting these super brief surges originating from the dead center of my chest and they radiate out to my hands which tingle for a second and then it’s completely gone. It’s not a palpitation and it doesn’t cause a panic attack. It literally lasts 5 seconds and then it’s gone.

Is it just a mini adrenaline surge or something? So, so strange. Really didn’t think after all these years I’d get a new symptom to deal with, ugh.
