What Causes Numbness, Double Vision, Headaches And Cognitive Issues?

I have been having symptoms of left side numbness, double vision and blur, headaches, cognitive issues, memory loss, and a strange sound of rushing water in my neck. I ve had multiple brain MRI s in the past that have showed a few lesions in my frontal lobes. I just recently had another brain MRI that only showed one large legion located in the back and no other legions were seen. In this most recent scan they noted that they have found a fetal PCA. With this not being in any other scan previously is this something to worry about? Do these sound like normal findings or should I try to look further into this? My doctor said that if my EEG comes back normal we are most likely diagnosing this as anxiety. I have severe anxiety and panic disorder and none of this compares to what I normally feel with anxiety.
