Hi Colleen. I've read all the above categories. I rarely get headaches. I also do not have nausea as a rule. I have Meclizine and it does not help , just makes me tired. I also have a antidepressant Celexa that also makes me feel terrible and does not help me at all. When I'm sitting, sleeping with some tossing and turning I'm not dizzy at all. I can drive without problems. I have had little relief for the past 17 months. I think my problem is cervicogentic dizziness. Those are my symptoms almost exactly. I think my problem comes from my neck. I have several bone spurs on the right side of my neck. I've been doing vestibular exercises faithfully for the last year. I've also walked 100 miles per month since the covid lockdown 3/11/21. The neurologist I saw a few months ago thinks I have some kind of virus and that it will just go away. I have had several tests with a vestibular physical therapist motor control, sensory organization tests and I have great balance. I've had 4 Pfizer vaccinations. Doctor's do not think it's a cause of my dizziness. When I'm at home trying to clean my house I really get dizzy with bending over, looking down, tucking my neck.....not sure what I can do at this point. I really appreciate the comments from other's that have dizziness, gives me some ideas to think about. I practice all the vestibular exercises daily with balance practice. While walking I do a lot of walking backwards, side to side neck/up and down....I live in Spokane, Washington and my next move is seeing a Neurologist in the Seattle or Portland area.
