Need help!

I am a 35 year old male, relatively healthy but do have asthma, had a bout of shingles a few years back and was diagnosed with EBV two four years ago.

For a few months now I have been tried, abnormally tired, like absolutely beat at some points despite not having done anything physical. I have severe brain fog and difficulty concentrating. I was experiencing a burning sensation on the side of my left leg, this eventually spread into numbness in my left foot but passed after a few hours. Since then, the numbness has appeared in my right arm/hand. I have had numerous episodes of this and it seems to be increasing.

My thyroid tested normal, vitamin levels were normal, every single test so far has been normal with the exception of an EKG. I had a bradycardia. They put me on a heart monitor and the results showed 38 - 180 though most of the time I was in the 70 range and one episode of a tachycardia. The cardiologist reviewed everything and does not seem concerned, she believes whatever is causing my symptoms is not due to my heart.

I have seen a neurologist and preliminary tests have come out normal. He believes it is highly unlikely that I have MS but ordered a brain scan to be sure. I go in for the scan in a few weeks.

I am really struggling with all of this. I work a high stress job and haven’t been able to work due to these issues it has been debilitating. Any insight or advice would be a huge help. This has been going on for months now and I just need some answers!
