Brief Answer:
Conditions such blood pressure changes to consider.

Detailed Answer:
Hello and thanks for using HCM.

I have read your query and understand your concerns.

Since recent brain scans didn't showed any brain metastasis, other conditions that may explain your symptoms need to be considered.

In my opinion first thing to evaluate is your blood pressure and its changes with body positions.

It is necessary to monitor your blood pressure in different body positions and in different times of the day.

A Holter 24 hours monitor ( blood pressure and heart rhythm ) could give valuable information.

Other conditions to consider include anemia ( blood tests needed ) and inner ear dysfunction ( benign positional vertigo, Ménière's ) by consulting an ENT Doctor.

First, these issues is necessary to be discussed with your primary care Doctor who can order appropriate tests regarding to your condition.

Hope you found the answer helpful.

Let me know if I can assist you further.

Greetings.
