I am 7½ weeks post op. I went back to work at a sedentary job 3 days a week at 4 weeks post op. My commute is 70-90 minutes each way. I am doing PT but nothing too extreme. I have been taking duloxetine for depression for about 6 months which makes me tired also. I am having night sweats. I am exhausted. Now that I look at this all written down, I can see why, but I don't remember being this tired when I had my first hip replacement 2 years ago.
