Question: Hi. I am a 32 year old female who recently had a spell of dizziness (about 4 weeks ago) while I was seated on my couch. I am a regular runner and had done a long run that morning in the XXXXXXX heat, so I kind of thought that I might be dehydrated. I went to a local quick care clinic and they ran bloodwork, a urinalysis, chest x-ray and ECG - all were normal. I continued to worry about the dizziness and the following day, began to feel odd sensations in my legs...almost like they were falling asleep, but not really. I went to a CareNow the following week since I had not been able to see my PCP and the doctor there did a few neurological tests and everything was normal. She recommended i see my PCP if I didn't feel normal in the next few days. Fast forward a week and I still had some "numbness" in my legs and seemed to get spells of dizziness (mainly when stressed about my condition). My doctor was concerned about the dizziness and ordered a brain MRI without contrast. I finally got the report and it indicates: no acute abnormality, tiny fluid signal intensity lesion involving the left parietal white matter. This is not entirely specific but may reflect a dialated perivascular space or lacunar infarct. I received my images and do not see anything that looks like a lesion, And ended up going to the neurologist, who doesn’t see anything on the MRI and thinks it is just the way my brain is and mentioned that some radiologists are more likely to point out “hyperintensities” that are not actually that. He did a series of neurologic tests and did not see anything that concerned him. Any ideas on what this sounds like? I am really nervous about it.

Is there anything that you can think of that can be causing these symptoms without an MRI abnormality? Multiple Sclerosis is one of my big concerns, along with ALS...

My muscles actually have been twitching more than usual over the past week or so. I am still running the same mileage and lifting the same amount of weight that i have in the past.and I noticed that the twitching started after i started taking a vitamin B supplement.

I am scheduled to go back to the neurologist in late-October for a follow-up. If I am still experiencing tingling and it is a nerve problem, could there be a chance that I lose function of body parts that are experiencing nerve damage (if that is what the tingling is)?
