What Causes Slurred Speech And Tingling Sensation In The Body?

I periodically I will have my speech affected by my brain feeling garbelled up and not being able to find words. I was told I have fibromyalgia 3 years ago, but about 6 months ago had some tripping episodes and pins and needles going on with numbness, saw my pcp and he did an MRI because he said I had MS red flags after hearing everything and is sending me to a neurologist. I might ad that about a year ago I had several episodes of losing my bearings and sheer panic because all the sudden I was lost and had to look around to try to get familiar with surroundings driving home from work. It did not last long but freaked me out. HELP!
