Hopefully the walk-in can help! Going to weigh in with some experience re: numbness. Out of nowhere over the last two years, my left arm will suddenly get super sensitive/numb, ditto my fingers. I've been to osteo for it a few times and inevitably it comes back to muscle tension, specifically in my neck/elbow/armpit area that ends up blocking nerves and doing it.

If you're worried it might be anxiety, maybe it's having a physical effect on your muscles? Hopefully whatever it is, it's a quick fix!
