Most every day I feel light headed where it feels like if you re on a boat or ship one feels dizzy or light headedness, not dizzy where things are twirling. It happens most often while Im driving or today Im home and I feel like that so I lay down and go to sleep and will feel better after I sleep. I feel like this most days and been happening 9 months now. Drs don t understand what s happening. Was sent to a physical therapist and told me to lay this way and sit up fast but I didnt get lightheaded than. Please help me this is interfering with my job and daily living. thank you. What kind of Dr. do i need to see? what needs to be done Thank you.
