Here's a new thing I've been getting that can be kind of freaky. You know when you're looking down from something high or you get the sudden feeling you're going to fall off a chair? Do you get that sort of sharp, sweaty sensation in your arms, feet and other places? It's not exactly a pain, more like the nerves are really cold and hot at the same time, or just sensitized. Well I've started getting that during panic, sort of focused under my arms. Feels weird and makes me worry about my heart, though I assume it's something to do with the sympathetic system or the vagus nerve. Anyone else get it when they get scared?
