its either a piece of glass or a metal shaving off dh's boot. I'm thinking glass though. I normally wear flip flops in the house but yesterday was barefoot and I felt something go in my foot. Its my right one of course...the one I have lost some motion in the ankle due to repeated sprains and a possible break. So I can't get my foot turned to see if I can see anything and I can't feel anything when I scrape my nail over it but I feel it when I walk! Maybe I can get dd to take a look today and see if she sees anything and if not hopefully it will work its way out soon!
