Sounds like you are doing all the right things, plus your attitude is great and you are going to the gym . You are the perfect student . You will be fine . I wasnt aware you were having a bilateral. You are so brave . And I read that this decision was thoroughly thought out . We will be here for you. Before and after. Never to early for stool softeners ! You remind me of me . Very prepared !! And with a positive disposition. Honestly my single tkr has gone relatively easy but I dont know about bilateral , only for the fact , both knees are injured and recovering. So its foreign to me . Wishing you all the best . Take advantage of the rehab center. Just rest , ice and elevate ALL DAY. With the occasional walk and very light exercise. Dont underestimate the energy drain and lack of sleep , they are brutal . Best of luck . ICEMAN
