I had a few dizzy spells yesterday and it was odd. The first I was lying on my side reading a book and was adjusting my position and rolled half onto my back and got an odd sense of pressure in my head. It went away as soon as I went back to my side. The second time I was just sitting on the couch talking to DH and felt like I was going to pass out. It took a minute or two for that one to subside after I lay down.
I'm glad I have an appointment with my MW today.
