Nope. Your level was too high...if it was an epidural. Are you sure it wasn't a spinal? Because it's very common for women with spinals to feel like they can't breathe. Hmmmm...re-read your birth story (thanks, btw...

), it sounds like you indeed had an epidural but that they dosed it too much for your c/s.
For labor, you're not supposed to be 'numb' from an epidural. You should be able to move your legs, feel pressure, be able to push, etc.. For a labor epidural that they dose for a c/s (commonly use xylocaine w/epi), you should be truly numb up to just below your breasts, able to breathe. It's common for bp to drop w/either kind of anesthesia, especially an epidural that they dose up to spinal capacity.
Long and wordy....sorry. Hope that explains things a bit.
