Good Evening, About 2 days ago my dog was tied up outside and when I went to bring her in she saw a bird and ran off causing her spike to come out of the ground and hit me in the lower calf of my left leg. Instantly it swelled up like a golf ball and hurt very bad, the skin didn t break but it turned purple covering my whole calf, it was badly bruised, it still hurts very bad and there is still a lump that hurts to touch. I figured it just broke a blood vessel that s why the bruise, but the knot I feel inside is what concerns me. Could this be a blood clot?
