i am a 60 yr.old female. 25 years ago i had a vestibular section in minnesota. everything went well. one year ago i started getting some symptons back ...living in a fog and dizziness. started doctoring again in Montana. nobody here could figure anything out so looked for dr. back in minnesota made a appt. and went back to see him. Did all the usual testing they couldnt find anything. one sympton i have is when sleeping i wake up from a falling sensation and swimming sensation and ringing of the ear. it happens several times a nite every nite. last week i thought i was having a heart attack with usual symptons chest pain arm and back pain. 2 days in hospital and they couldnt find nothing. when i tell them about the sensation in my head they couldnt figure out anything. sometimes that fealing feels like it radiates into my chest. it lasts only a few seconds. i just woke up from nap with that again...feel like im going crazy and i dread going to sleep. maybe you have some thoughts?
