For two weeks i have been experiencing intermittent speach problems. At times i have a hard time beginning speech, I feel like the muscles in the throat contract and the words are hard to pronounce. After a few words it goes away and I speak normally. I have also experienced weekness in my arms on two occasions, not being able to pick things up. It lasted just for a few minutes. i am not sure what to do and I am very concerned. Any info would be greatly appreciated.
