Hello,
A couple weeks ago, i was walking down our hallway in our home and all of a sudden I couldn't walk a straight line, I kept wanting to go to the side. It scared me pretty bad and I had my husband take me to the hospital. They ran some test, ekg, chest xray, bloodwork, cartoid ultrasound and a ct scan. The only thing they found was a lacunar infarct of uncertain age. The dr. told me she thought maybe it was my inner ear since the lacunar infarct was old and on my left side and the part of the brain that controls balance is in the back. I then went to a neurologist for a second opinion. He told me thought it is inner ear also. He then sent me for a ultrasound on the back of my neck to check the vertebral arteries, the technician said it looked like I had a narrowing on the right side. The neurologists nurse called the next day and told me they want to do a mri/mra with contrast, scheduled at the end of the month. When I then wrote the neurologist himself, he told me he wanted to check the arteries but odds are they are not narrowed and the ultrasound suggested they are but the ultrasound is often wrong. What is your opinions?
And has anyone ever had the mri/mra with contrast and how was it, any allergic reactions, and what it entails? I read up about ultrasounds but cannot find anywhere where it says often wrong. My mom told me she also had this a few years ago, where she couldn't walk straight and they told her inner ear.
I don't go for mri till end of this month so I have a lot of anxiety. Thanks for any help you can give me.
