should I be worried?

I have not been told that I have MS. HI!  I am a 33 year old professional that found out last January that I have around 15 - 20 white spots throughout my brain.  Of those spots, about 8 are more significant.  They have tested for MS and other things and it has come up negative.  I have not had headaches in the past.  the past two months... I get home on Friday and I go right to sleep and pretty much sleep all weekend.  During the week, I am to get the job done, but it is taxing.  My latest MRI did not have any changes.    Thoughts... I need direction.

We can't diagnose you here.  I can see you are very anxious.  This is a very quiet forum.  I am sorry your post wasn't answered fast enough for you.  I can't imagine what could have caused you to have 15 - 20 white spots.  What did your neurologist or doctor say about these spots?  Is there an explanation? 

Please make sure you get a copy of your MRI and the corresponding report.  You can always take this for a second opinion.  What are your other symptoms? 

Your symptoms would be then:  lost words, fatigue, and fine motor coordination loss. 

These certainly could be MS, but they could be from any number of disorders, diseases, or syndromes.  What did your doctor way was causing all those lesions? 

MS is a disease of exclusion.  You only get an MS diagnosis once everything else has been ruled out.  What tests did you have?  Did you see an MS specialist?  If you didn't, then you may want to take your MRI results and see one.
