Congratulations!
This is kind of a funny story, but the last time I lost a ton of weight and got to 166 pounds (10 years ago), I was crossing my legs all the time, not thinking that it's really not good for your legs. Anywho, I started to find that one of my feet was constantly tripping or I would stub the toe of that foot. Being a bit of an internet hypochondriac, I suddenly had myself convinced that I might have MS. I was so upset and went to the doctor who told me that drop foot comes from nerve damage, and while it does occur in MS patients, it's also seen a lot in those who have lost a lot of weight and suddenly go overboard with crossing their legs! Sure enough, I laid off the leg crossing for a month and I stopped having drop foot. Sigh, I'm the queen of too much of a good thing.
