Yeah, I get this too. I think mine can be from different things. Is yours definitely tightness in your throat or neck? Or does it feel more like your chest can't expand to get enough oxygen? I've found massage to be very helpful in any case, there are trigger points on my back and neck that they press, and it's like a knot releases. Believe me, it's cheaper and more effective than going to the doctor! When I went to the ER complaining of shortness of breath and feeling lightheaded, they kept me around for a few hours, patted me on the head, and dismissed me with a rx for Valium and a bill for $800.
