What does hyperacusis feel like?

What does it feel like to have hyperacusis?
If you have hyperacusis it might feel painful or startling. It may make you feel angry, distressed or anxious. You may find yourself panicking when you try to get away from the sound.
You may find that after being exposed to an uncomfortable sound the discomfort continues for a period of time afterwards and becomes worse if you hear the sound again.
Your reaction to an uncomfortable sound may be made worse if you are in an environment where you expect to hear the sound. When you are afraid of hearing a sound, you may become anxious, which increases your discomfort, and when you are afraid or stressed the brain produces substances, which increase the sensitivity to sound.
However, everyone reacts differently to hyperacusis.
