Numbness in Maxillary Nerve Region.

I was playing basketball guarding some guy and he somehow elbowed me hard to the upper left cheekbone in a narrow region. It didn't cause much swelling at all, just a very solid 1x1 or so dark black eye spot that 5 days later is still here, but it initially made my left side of my face instantly numb and my vision was very cross-eyed/strange. Then it got better after 20 minutes, but the area left of my left nostril and upper left lip is still about 50% numb. I looked online and this area is the ends of where the Maxilary nerve goes in two places (right where I feel numbness). Been a bit extra tired, and had minimal blood up my mouth the first three days (like post nasal drip), but that basically doesn't happen anymore. Otherwise I feel fine. How long should I expect this numbness to last? I have full motor skills and can even somewhat feel the numb areas it is just annoying mostly.
