generally it is safe as long as you have no pain or massive swelling from prolonged wear.if you wear either one too tight for too long a period irreversible damage could occur.i only had one instance that scared me and that is when i woke up in the middle of the night with a ring on and i was swollen so large i thought i would not be able to get the ring off.haven't worn a ring all night since!my advice is take it easy at first,make sure you have the right fit,and enjoy!
