I have definately been thrown into a panic attack by loud noises. Mostly the "sudden" type. I can be standing beside a construction site and be fine with it, but something simple like a pan falling off counter when I'm not looking and "boom". I *think* the wave thing is chemical related. Panic attacks are flight or fight responses of our bodies, and the body releases adrenaline and other chemicals... and like anything they have to run their course.
I'm not procrastinating----I'm still doing yesterday!!!!
I have no medical training, any medical opinions expressed in my posts are just that....opinions.
