I feel sluggish, foggy, not my usual self.
Chronic pain is awful.
In IC, it is compounded by the fact that you may rarely get a good night's sleep, and people around you don't believe or understand what you're going through. For all these reasons, it's common for people with IC to feel depressed. Successful treatment for the physical symptoms of IC may clear up the mental health consequences. As far as it is known, IC is not contagious. You didn't get it from someone else, and you can't give it to anyone else.
