Hello, my mom had a headache last week (severe) and she was dizzy. We took her to ER. They did CT and MRI. She has a 2mm aneurysm in brain, The doctor said, she should keep an eye on it. They send us back to home. This week she still feels very dizzy, shaky and tired all the time. She just wants to stay in bed. I am very worried about her. Do you think, it could be something more serous? She also had pressure in her ear at one point but right now no headache or ear pressure.
