I was sitting at my computer just a few minutes ago and, all of a sudden and for no reason I can think of, I got a strange sensation in my right leg. It felt as though a stream of cold air was passing over it. The sensation lasted for a few minutes and then stopped. My left leg is fine. I’ve already booked a doctors appointment (can’t be too careful), but I’d be keen to know if this kind of isolated and temporary sensation is common, and if it can be symptomatic of anything serious. If it helps, I’m a 25 year old guy with no serious pre-existing conditions.
Thanks in advance.
