What Causes Numbness And With Hematoma On Ankle?

Just unsure how concerned to be about numbness with a hematoma - I was hit in the shin, just above the anklebone by a field hockey ball shot by my daughter about a week ago. Had significant swelling initially, which has become a diffuse bruise measuring about six inches in diameter, wrapping around my ankle. The numbness in the center is also white, and the tissue is thicker than the rest. Being that it s late on a Thursday, and I have to go into work at 4:45 AM tomorrow and work all day an hour from my medical facility (and then it s the weekend). Trying to figure out if I should cut the day short and come back and be seen. There isn t significant pain at this time, other than when pressure is placed on the bruising, or I rotate the ankle. My toes are fine.
