I have a serious itching problem on my body. It usually happens in winters. As soon as I wear some woollen clothes,itching starts in my whole body...from head to toe. And it is of kind like you've eated by thousands of ants at same time. When I get excited or laugh for more than 2minutes, while taking the hot shower,while eating the hot food or while drinking some hot beverages the same thing happens to me. Sometimes while sleeping it starts and that is the worst nightmare for me. Waiting for some suggestions. Thank You.
