Over the last couple of years and more intensely in the last six months my hearing is so hypersensitive. There are now some sounds I cannot tolerate at all. Opening a pop can, high pitch sounds, even the simplest of sounds can feel startling to my nervous system. And bonus I now have a constant ringing in my ears.
My RSD started in my foot, ankle, leg after back surgery, and has moved all over since 2004.
So sorry that this is happening to you
