I'm having vertigo when i lay down on bed, when I'm standing or seated i feel fine but as soon as i lay down everything starts spinning. It started from yesterday morning, last night I couldn't sleep so l checked online that it might be ear issue and as per one post i used 2 pillows to keep my head up l did not feel vertigo then but when i do not use any pillow or use only one i feel like vertigo. I noticed one more thing that vertigo/dizziness gets intense when i sleep on right side but it minimizes when i sleep on left side (but still feel it if using 1 pillow). What might cause this and Is there any medication?
