Lenovo — T440p laptop is generating radiation in my left hand

Address:

Hyderabad, Andhra Pradesh

I am using T440p laptop from last 3 months. I started realizing that the great amount of irritation in my left hand while using and after using laptop. I thought its the problem with the fan. So, fan was replaced as its under warranty. But, the problem still exists. I believe that its not a simple heating, but, its generating great amount of radiation, which is resulting the irritation throughtout the day. These days, I am not even touching the keyboard with my left hand, using a glove for timebeing. Please let me know what to do?
