I used to get swollen ankles a lot when I lived in Bermuda, plus still do a little bit. When I started my diet my ankles were terrible for a few days, think this was down to my body trying to balance the water. If I dont drink enough now I still get a bit puffy. Unfortunately, I know now that this is a sign of age too (booooo). I would up your water a bit, you may be retaining if you are not drinking enough.
