Is it normal that my back tenses up with no control over it?
So I have noticed my back is tensing up UNCONTROLLABLY at awkward times. For example; When I hear bees buzzing around me, my back tenses up. Also when I was getting my hair cut, hearing the clippers and the blow dryer behind me ( like around my neck). Its really wierd and I make up and excuse as to what happened. I don't know if it happens to anyone else and I'm too embarrassed to ask anyone about it. When it happens I have to try and fight it from happening. But it can happen over and over. It's like my upper back goes out and my stomach goes out and my lower back goes in. Its wierd!!!
