Last night, I was laying in bed watching TV and all of a sudden, I felt a wave of dizziness hit me and my whole body suddenly got really uncomfortable feeling.. kind of prickly and weak. About a minute later, I started feeling like what seemed to be rapid eye movements and had trouble focusing. It lasted about a minute, then the feeling of eye movments went away and about a few minutes after that the dizziness stopped. I was fine after. Today I had a pretty bad headache and body ache but that's all. Does anyone know what's going on?
