MRI results

[Shoutout]

Hello all.
I would like to share my story, hoping to get a helpful response from the experts here.
I am a 40 year-old male. 3 weeks ago, i started feeling numbness in my right hand which reach my left hand a couple of days later. Then my feet started feeling numb as well, 2-3 days later. I got spooked and went to the ER where they did a CT scan for brain and cervical spine, both came back normal. Reason they did CT scan is that I told them I had bumped my head a week before and suffered what I believe was a minor concussion.
Basically doctors dismissed me and sent me home based on the CT results.
A week later, since symptoms didn't improve, I consulted a neurologist who ordered MRI without contrast for brain and full spine. It came back normal.
He is confused as why I have such symptoms and kept reassuring me that it's nothing serious.
However, I'm finding it hard to sleep at night due to the numbness in hands mostly.

I am now wondering if my MRI should've been with contrast and that perhaps they have missed lesion due to lack of contrast. I am wondering if I should redo the MRI with contrast, or if it would be a waste of time and money.

Or perhaps I have MS while having normal MRI? I am confused and not sure what do. Any help would be very much appreciated.

Thank you.

Forgot to add, B12, vitamin D, RF factor, ESR, reactive protein all came back normal.

If your MRI without contrast didn't show any lesions the MRI with contrast will show the same...no lesions. Contrast is only used to see if lesions found on the non-contrast MRI "light up" with contrast which would indicate current inflammation. To ask for contrast when your MRIs were normal will not help you whatsoever and is a waste of money.

Welcome to ThisIsMS. "Normal" is often just a statistical derivation of the 95% confidence interval of the population of current test results. As such, you could be +/- 2 standard deviations from the population mean AND still have a "normal" result and not necessarily at a healthy level. Some tests are more problematic than other in this regard, e.g., in particular vitamin B12 and D3. A good healthy B12 result is 500-1000 pg/mL and D3 should be around 50-60 ng/mL. Do you have data for your lab results? If so, then it would be helpful if you're willing to post them.
