Anytime I crouch or bend over for a few minutes, I am very dizzy when I stand up. This has happened since getting on Coumadin - noticed it again today while painting a small end table (it didn't smell, so it wasn't the fumes!). My blood pressure is fine. Does this happen to anyone else? I expect it has something to do with compressing blood vessels as I crouch. I have young children and a small dog, so I crouch down frequently.
