Sunshine really helps with the mood even when you feel tired. Sleep was elusive and itching at incision which I know is normal and healing but I want to sleep.
I'm lucky that I moved several years ago to Southern New Mexico from Indiana with abundant sunshine. I'm sorry that you're not sleeping well and feel itchy, and you're such a trooper for going through four joint replacements.
Groin pulling from some of these mainly due to lack of motion pre surgery. In recliner and icing now. Tired. No more exercises for the day except walking to the bathroom the long way - about 50-60 steps.
Be well and I hope that tonight you get some well deserved rest...
