my wisdom tooth is half black and half white and hurts like hell but also all of a sudden I can't open my mouth all the way and it's painful to swallow, the side of the tongue where the wisdom tooth is hurts and feels sore all around and is hard to stick out..are all these symptoms from the wisdom tooth?

It's time to see your dentist. Yes, a wisdom tooth can cause these symptoms. It's time to get it extracted.

how are they gonna extract it if I could barely open my mouth?

You need to be put on an antibiotic first, to get the infection under control. Within 48 hrs of being on an antibiotic you should slowly be able to open more. Until then rinse with warm salt water, it should help.
