Swollen ankles

I have been on levemir for a little over a week and my ankles are very swollen. My sugar levels are much better, but it seems to be making my feet swell. Has anyone ever heard of this? I am out of town and cannot go seem my doctor until August, so I was just wondering if it was a side-effect that will go away or something more serious that I should go to a clinic to have looked at. Any help would be great!!
