Seems everything triggers it like car doors, house doors & cabinets, tv quiet in background, footsteps walking around house or stairs, etc. It's like it's all amplified. Incredibly annoying & makes me jumpy & angry. Hurts my sinuses & eyes. Makes my heart jump so that hurts too.
I don't have pain from sounds but I do get sensory overload. I use 'eargasm' ear plugs now and it really helps. They are more expensive than the foam ear plugs but they allow me to hear and talk to people while decreasing the louder background noises.
