My doctors office instructions said to wear during the day, off at night. Hospital instructions were the same. I actually sent a message through OS patient portal yesterday to see how long ( as in a week, month, etc), I needed to use them. Nurse called and said to use them until my first follow up appt which is Wed and that will be 2 weeks postop. She said they will see how I'm doing then and if all is well, I can stop wearing them.
