What Causes Tingling Sensation Around The Neck?

Hi, I am 22- years-old. I feel tingling around my neck and at the back of my head;whenever I take a deep breathe my upper back makes cracking sounds , and sometimes I sense a slight pressure and wierd sound inside my nostrils, unlike that of a common cold or a flu ; and it is very discomforting-specially on morning. it started around 2 months ago, and it is getting worse everyday and I am having more and more difficulty concentrating almost on everything. I was thinking to see a doctor but I was not feeling any pain other than the discomfort, so I decided to wait. Could these be early signs of a serious problem?
