Hi, I Had My Hysterectomy, Cystocelene And Rectocelene On February

Hi, I had my hysterectomy, cystocelene and rectocelene on February 18, 2015. To date, I am still feeling like I have sea legs and now that I'm back at work I have to get up and walk for about 5 minutes to rebalance, is this normal? I know everybody is different, how long does this last? It seems to also happen with the passing of gas, could this be my pudendal nerve acting up?
