Welcome to the forum.
I have awful night sweats. I have for years. I was diagnosed 3 years ago, when I was 29 years old. Hardly a night goes by that I don't wake up completely drenched. I never had a problem with this before Crohn's. Usually the sweats come with the chills for me. Strange, huh? I've never achieved remission but I would imagine this would be something that would go away once you're in remission.
