Welcome to Crohn's Forum, a support group for people with all forms of IBD. While this community is not a substitute for doctor's advice and we cannot treat or diagnose, we find being able to communicate with others who have IBD is invaluable as we navigate our struggles and celebrate our successes. We invite you to join us.
I have a number of friends who have this, actually! I only experience it if I'm having a migraine day, since then I become especially hypersensitive to sound.
I also get this when I have migraines, but only then, I can't imagine what it must be like to get that all of the time *hug*. Im sorry I don't have anything more useful to add, I just wanted to show you my support.
