at night one or both arms go numb-starting at shoulder and down to my fingers, my shoulders feel very tight and have limited movement in them lately, sometimes my arms/ hands will go numb sitting at work doing nothing and it lasts all day, now i am experiencing weakness in my hands and legs, hard to pick up small objects or button coat etc.. I am worried it coudl be MS symtoms
what type doctor should i see to get tests to see what this is
thanks
