Wrists

So i can't remember if I've posted on this before but I've got some new wrists guards/braces and i've found that if I don't wear them to bed at night then the next day my wrists hurt wicked bad. any ideas as to why that would be? i'm almost afraid to not wear them to bed, and i would rather not become dependent on them. I carry my arnica with me everywhere just incase they start to hurt also. The pain starts in the base of my wrist on the under side and either goes into my arm, my hand/fingers, or both. Any ideas, just comment. Thanks :)
