I continue to wake up with swollen mouth lips, can be my upper lip or lower lip always happens while I am sleeping, I sleep fine, no problem falling asleep. Sometimes its my tongue but it gets so swollen I look disfigured and takes 24 - 48 hrs to go down, it does not hurt or itch or bleed or get blistered. Someone told me its stess I my brain keeps going even though I think I am sleeping fine, not crazy dreams and not restless. It can b e so annoying cause I never know when it is going to happen
