about 3 weeks ago the tip of my right index finger became numb. Then I started getting tingling in my hand, fingers up to my elbow and back down. I do clerical work and type a good part of my day. It really seems to get worse when I type. I have started wearing a brace and it seems to help but it has never completely went away. I am afraid it may be carpal tunnel but I was told it usually effects more than just your index finger. My finger tip feels hurts like it is bruised and the nail is very sensitive.
