Hi Laura, We were up every 3-4 hours last night too, but able to go back to sleep. I think that we got up at 5 this morning and it already feels like my body has gone thru an entire day's activities. I did my exercises this morning and now the knee is hurting and having those little "sticker like" pains it. I don't know if that is nerves or just sore tissue. Guess it doesn't really matter which it is. I just made myself a comfy place on the sofa to lay down, elevate and ice. It feels so good right now to have the ice on it.....It's really odd how one day we feel really good and the next, not so much. For me, it comes in waves throughout the day.....I'm waiting on my OS' office to call back about a pain med refill. I run out today, so I'm hoping that it gets taken care of. Otherwise, it could be a really long weekend....Good luck with your PT. If you feel up to it, let us know how you are doing. Vickie.
