If its hard then it very well could be either a tumor or cyst. Most cysts are full of fluid and just form on the skin rather than inside the muscle, but can form there as well. Infections would have redness like D said. You definitely need a vet soon. If it grows too large it may split the skin of the leg and you really don't want that on your hands. That. will lead to infection or worse.
