Hi Jenn and welcome,
Your actually brain MRI isn't specifically meaningful, a couple of non specific lesions in the frontal lobes isn't usually classed as abnormal findings, so your brain MRI wouldn't be suggestive of a neurological condition like MS causing your symptoms.
Keep in mind that when ever you google things like numbness and tingling, neurological conditions like MS are always going to come up but MS is not the only cause or the most common cause so try not to get concerned that it could be something like MS at this stage. Actually If your saying these symptoms are in all peripherals (hands and feet) and only for a short duration of a minute or two, these are common red flags pointing away from conditions like MS so what your likely to expect is further tests to try and work out what's going on...
Hope that helps.......JJ
