Hi Karissa,
Dancerindenver is right, you can't create a signature until you've made a certain number of posts - maybe around 20, but I'm not certain.
With your strange weight gain I would say, keep in mind that your weight fluctuates by around 2lbs throughout the day anyway, so try to weigh yourself at the same time each day. It sounds like your tough workout may have caused some fluid retention around your ankles if you're hobbling - this could be causing some of the lbs. It also sounds like your diet over the weekend was quite high in salt, and that can add to/cause fluid retention.
Try not to worry about it too much, as it is essentially a very minor set back. I would suggest an epsom salt bath to temporarily get rid of water retention and see if that helps you out
Good luck! Feel free to pm me and let me know if my advice was any help at all
