@Sabrinab - Welcome to our forum! It definitely sounds like you have vascular compression of some sort. Your stroke-like symptoms would be more related to the internal carotid artery, but the head pressure, off balance feeling & brain fog more relate to internal jugular vein. It is rare, but we’ve had members w/ both.
The doctors you need to see at Kaiser are:
•Dr. Brian Jian (Neurosurgeon) & Dr. Balough (Neurotologist) & Dr. Ji (Neurosurgeon/Neurointerventional Radiologist) - KAISER SACRAMENTO, 6600 Bruceville Rd, Sacramento, CA, 916-688-2000
You’ll get farther with one of them than w/ whomever you’ve been seeing who told you nothing is wrong.
Since you’ve posted on the forum, your account has been upgraded so you can now post images. Please show us what you’ve gotten so far. We aren’t doctors here but we can give a non-medical opinion about what we see.
