Jeni I misread that and though you said 5 bad foot days lol.
I agree I think your 2lbs is likely your cast, so count it as a stay the same and jump (well not literally) back in today, you will soon be losing again. Also you might not be able to walk for miles but using crutches will use more energy than normal walking so try to get out for a shuffle even if it isn't far.
Edited because my predictive text inserted snuggle, instead of shuffle. Now I recommend snuggling just as much, but it wasn't what I meant ha ha.
