Hello...I m 64 years old, and 4 weeks out of surgery to repair a broken tibia. I m out of my cast, and now wear a leg brace, although no weight-bearing. X-rays showing good bone mending, and otherwise quite healthy. However, lately I ve been experiencing increased fatigue and slight nausea. I can t seem to get enough rest and sleep. I take T3 occasionally for pain. Question is: why am I feeling so much more tired than In the earlier stages of my recovery? Thank you.
