I have slight tingling in left fingers after a deep breath. Can t make it happen it s just now and then. I m 41, fit and healthy, work outdoors in sport 5ft11, 13st, not over weight, work outoutdoors, eat healthy but just suffered my first anxiety panic symptoms ever a month ago, kind of over the episodes now with no medication just by mental positivity and support from my wife. I pushed docs for an ultrasound at the time of panic type symptoms , chest pain, anxiety, etc and they found slightly thicker very slight enlarged but all readings from 24hr ECG and blood pressure ok, they are happy with. Have been reading about issues with anxiety, neck muscles and nerves causing this tingling here and there but without any anxiety symptoms anymore I m puzzled and worried.
