Its so hard sometimes trying to figure out these things. I remember one time I had Shoshi to the Vet several times, she had x-rays, bloodwork, you name it, it was done. As it turned out there was a small piece of harden mud shoved way up in between the pads of her foot. It was hard and no doubt sore. The thing was I knew something was wrong but she didn't give me any good hints. I finally just happened to discover it, but once I did she was fine.

I so hope you get an answer soon and that its nothing serious.
