Welcome to Healingwell!
I am so sorry for the delay in responding. I have had a rough couple of days! (and it seems a little slow around here on the weekends-must be all those summer plans)
I have had several white matter lesions on my MRI and have not been diagnosed with MS, I have been told that this is common with migraines and are benign. Do you have any type of symptoms to make you feel like there's "significance" behind these white matters? You stated you haven't had a headache but it sounds to me like you struggle with normal tasks and have to "recover" during the weekend--can you elaborate a little? Maybe someone here has a similar story they can share?
I have a terrible headache now and am heading to bed...i will be back on tomorrow.

also "White spots on a brain scan could be caused by several different factors. One possibility could be a hardening of small arteries in the brain as a result of high blood pressure, causing a buildup of fluid. The spots might also be linked to an early onset of a stroke or other neurological condition, such as a migraine or MS. It is difficult for radiologists to diagnose white spots from an MRI scan, as there is only a small chance that they could be malignant and abnormal as opposed to benign. White matter can appear as a natural phenomenon of the brain due to the coating of axon nerve fibers with myelin, which gives it its appearance on a scan. Although in the majority of cases the appearance of these spots is not cause for concern, it is still recommended if in doubt to seek a consultation in regard to future tests to determine if they are symptomatic of a neurological decay, with multiple sclerosis or even a brain tumour as essentially worst case scenarios."
