I have neck stiffness at the back of my neck into my shoulders and my ears keep popping. with very light occasional headaches. any idea?

I can see the future: I can tell you exactly what will happen: It will get better, it will stay the same, or it will get worse. If it gets worse, you should see a doctor. If it stays the same, it depends on your level of discomfort. If it goes away, as the Aussies say, no worries. Are you undecided about the doctor or just reluctant? I mean, the NHS must be good for SOMETHING, no?
