3 Weeks after Surgery

Is going back to work on Monday such a good idea or am I just reluctant to give up my relative freedom (if being trapped inside during the winter constitutes freedom)?  In any case, after doing a morning of errands and chores, I'm utterly exhausted.  On the plus side, however, I descended the stairs normally for the first time with 15 pounds of laundry on my back no less.  I'm still not strong enough to climb them.
