And vice versa. There has been a very old argument as to whether the sleep disorder or the pain comes first! the sleep disorder that is one of the diagnostic criteria seems to involve an imbalance between rem (dream) sleep and the deepest stage of sleep (stage 4) excessive dreaming is common and the feeling of awakening feeling like you worked all night is common. Tricyclic antidepressants are a treatment.
Yes. People with fibromyalgia tend to have trouble sleeping. Even if they sleep 10 hours a night they often do not wake up well rested. Without restorative sleep the body does not recover from the stresses of the day. Muscles do not heal and neurotransmitters are not restored. This leaves fibromyalgia patients waking up feeling tired and in pain.
