Suggest Remedies For Soreness And Pain In My Ankle After An Injury

I was hit on the inside of my ankle by a piece of wood, right on the ankle bone. It hurt, but I was able to keep working, not a big deal. About a week later, I find I have pain going up the inside of my leg, like a tendon maybe that runs about half way up my leg. It is very sensitive and is very sore. If I'm hit or bumped there or on my ankle it is extremely painful. Suggestions? Should I go get it checked out or just tough it out?
