•First I would start with the original issue, before doctors implemented there regimen of medicatIons and tests.

•You say you experienced high blood pressure/heart palpitations out of the blue and you are/were in overall good health.
I am curious if the first physician you saw, asked you anything about your current lifestyle? Any new added external or physical stressors and or how you handle stress in general? Sleep, nutrition etc...

•Later 40’s is a common age for females to start experiencing mild pre menopause symptoms, some of those can be heart palpitations and anxiety type feelings. Did any physician ask/check in on that area?

•High Blood pressure/Heart palpitations can be caused my many things. When someone presents to a doctor and a discussion is not throughly had, often the doctors first response is medications and tests as a precaution and to cover themselves of any liability.
This can in turn raise anxiety levels, which do not help high blood pressure/palpitations at all.

•As far as the MRI- I would trust the Neurologist as they told you it was not to worry about. Those are actually common findings and a radiologist is just doing their job to interpret everything they see on an MRI. Even their verbiage can cause people anxiety.

•Be very cautious on this site, to allow others to lead you down a path of making you more worrisome and unnecessary rabbit holes.

•In my opinion, it sounds like you were very healthy. Experienced an odd sensation, that was probably natural to timing in life or stressors. The doctors visits added or started something that was never there to begin with. ALL medications have some kind of side effect.

•Work with someone to get your body back in balance and back to its homeostatic state. And reduce the stress this has brought on you.
