I am experiencing vertigo throughout the day and wonder if it can be CPAP related. When I wake up I have very puffy eyes, headaches, feel spacey, and inside my ears are wet. I am suspicious that the CPAP machine is causing sinus and inner ear problems that are contributing to vertigo. I have turned down the pressure setting on the machine which has helped a little, but has not totally resolved the problem. I did sleep for two nights without using the machine and felt better, but I sleep better when using the machine. I'm thinking of consulting an ENT doctor.
