The first sign of oncoming stroke is the feeling of sudden weakness in the muscles of arms, legs and face. This weakness can be temporary or permanent depending upon the severity of the problem. Sudden feeling of tingling or numbness in the left shoulder or arm that worsens gradually is also experienced by many people in such situation. Sometimes these symptoms end up in sudden failure of the muscles when the effected person cannot lift his/her leg or arm. This weakness can also be experienced by the effected person after the occurrence of the stroke which compels him to remain immobile for long time.
