I find myself having problems pronouncing words. It seems that my lips do not move as freely as before. My memory is not affected, nor is my walking and other functions. HOWEVER, I notice that my right hand is frequently clenched. If I am typing or writing or eating.......it is ok. BUT, for no reason, I could be sitting and watching TV and I find that my fist is closed. Why.....is my question. When I recognize it, I open it and no problem, but then later on........it is closed again. Let me know your thoughts.
