Talk to General Physician on Tired Right Arm

I woke up with numbness in my right arm. Nothing unusual but it took longer than usual to go away. Since then I am feeling tiredness in my whole arm. Sometimes I feel my finger tips are still numb and giving tingling feel. I wanted to ask is it normal for this episode to be this long and what could I do to get rid of it? I hope its not a symptom for something critical. Thank You.
