This sounds like water retention. It could be something else though. Give your Dr a call as soon as you can to find out what's going on. You should not be having the bloating and swelling.
I had swelling in my legs too 2 days after surgery. I also had numbness in one of my legs and was so afraid I had a blood clot. I was told mnot to worry that the swelling in my legs were water retenion and that the numbness in my leg was probably due to the positioning during my surgery. 2 days later the swelling and numbness was gone. The bloating is to be expected. I am 2 weeks post surgery and still feel bloated. My sugesstion is not to eat anything heavy for a while. I did and I'm paying for it now. I am so bloated all the time and now the food just sits on my stomach causing a lot of pain and I'm not getting much of it out. Bowel movements are painful and few. But don't worry about the swelling. it wil go away soon.
