I talked to a friend last night who had several brain injuries years ago, and she suggested that maybe the dizziness I've been experiencing could be a migraine. It's possible. She had migraines that weren't even headaches. She would see smoke, then her words would start to slur, and then she'd start talking jibberish. I had migraines before my head injuries, and they've always been the same for me--I see sparklies, feel weird, then experience a searing brutal pain in my head, usually accompanied by terrible nausea and sensitivity to light. This most recent bout of dizziness, my head does hurt a bit, but not much. Instead, everything looks misty, my peripheral vision is kind of blurred, and then I have that falling upwards feeling. I also do have an increased sensitivity to light. Anyway, I'm feeling somewhat better today, so I'm just continuing my plan of resting, but if I continue to have this dizziness, I'm going to get some migraine meds! Just thought I'd share this possibility with others having the same problem!
