Could my symptoms and MRI scan be indicative of multiple sclerosis?

Hello doctor,

I am a 29-year-old man with a muscular, athletic build. I used to engage in distance running regularly and was in excellent shape. However, I began experiencing debilitating symptoms that impacted my career last year. These symptoms include heart palpitations, chest pain and pressure, nausea, muscular weakness, muscle spasms in various areas of my body, sensitivity to temperature, digestive issues, and other symptoms. I have a family history of multiple sclerosis (MS) and brain tumors. I underwent an MRI to investigate the possibility. Fortunately, no plaques indicative of MS were detected on the MRI. However, the scan did reveal some unusual structures extending from the back of my head to just behind the ear. These structures appeared as black voids, white signal activity areas, and masses of black squiggly lines. Notably, the appearance of this side of my brain, which I believe is the right side, differs significantly from the other. My physician, who specializes in nutrition, hormonal issues, and general practice, stated that it is not MS but did not provide further insight I have attached my MRI scan, which shows the progression from the back of my head to around the ear, with the areas of concern circled in blue, while the remaining areas are the original MRI colors. One image in the scan shows a view from below (possibly) with a spot of bright signal activity corresponding to the structures in the other images.

Although my physician reassured me that there is nothing to be concerned about, I am seeking a professional opinion on whether I should consult a neurologist to explore this matter further. Please help.

Thank you in advance.
