What Causes Facial Numbness, Nausea And Heaviness In Head?

I've been having an odd sensation in my head for the past two weeks. I've never felt this way before and it's hard to describe. It feels similar to motion sickness. My head feels heavy, I have faical numbness, and I have mild nausea. It seems to get worse when I move my eyes quickly or if I move my head quickly. Today I have had this sensation from 1:00 p.m until now which is 10:00 p.m.
