What Causes Tingling/numbness Feeling In Fingers While Having Runny Nose And Cough?

I have caught a cold two days back. From yesterday, my nose is running continuously and I was coughing a lot. Today at office while working I had this tingling feeling in my fingers and it felt like my hand was going numb. I was working in my pc and I felt unable to type properly. It also hurt at times and I had to make an effort to move my fingers properly. What is wrong with me? Please help.
