24 Year Old with sudden lisp

Hi,

I'm a 24-year-old male who a couple weeks ago began noticing myself having a hard time pronouncing S's here and there. My significant others couldn't notice it and so I just ignored it. A week or so later, however, I notice my tongue felt numb and tingling. I looked at it in the mirror and it appeared to be shaking. (Note: I have not noticed it shaking since that day, although it does feel numb). I went to the ER, they said they couldn't do much and scheduled something with a neurologist.

By the time I got to the neurologist, I had begun having fasciculations all over my body (presumably due to stress/anxiety more than a rapid onset of ALS). The neurologist didn't take my ALS fears very seriously after checking my body strength (although I obviously fear this would be a bulbar ALS case) which would show more weakness in the mouth. He scheduled blood tests and an MRI, as well as an x-ray of the spine. (I have had constant headaches for 5 months so we thought the two problems may be releated).

Now, another week later, I am having even more difficulty speaking, feeling a particular tightness in my chin. I can still speak relatively well, with a slurred word her and there, but I feel like I'm having to try too hard. I can still easily open and move my mouth, and shake my tongue quickly from side to side. Should I be concerned? And what should my next plan of action be?

Thank you so much,
Logan

I'm 23 and recently started experiencing similar symptoms (the slurred speech).  In a recent meeting at work it took me four tries to properly pronounce "transition" and my "s"s seem to be slurred.  

Do you have an update on your situation?

I'm 25 and I have noticed that my s's are getting slurred as well.  I notice it the most when I am signing quick phrases or talking loudly.

Do either of you have any updates?
