Good luck going back to work. I went back at 8 weeks after my bilateral, but used vacation and holiday leave so I only worked 3-4 days my first 3 weeks. Week 1 my legs (calves and ankles) we swollen by day 3 and I needed to ice and elevate much more on day 4. Weeks 2-3 were only 3 day weeks, which was helpful. I iced and elevated at my desk 1-2 times per day, as my schedule allowed.
Before week 2 started, I bought knee-high mild compression socks off Amazon (Dr. motion brand) and have been wearing those daily. They have really reduced the aching and swelling. I've been back full time for 2 weeks now and have not iced or elevated at all during work. Some nights I come home exhausted and need to ice and elevate the moment I walk in the door, and other nights I run errands on my way home, prepare dinner for the family, and then do other household chores when I get home with no problems. Just be prepared to adapt day by day.
