How Can i Help My Strained Chest?????????

I was in the back garden with my children and we have a back gate to a field. There has been some work going on in the field to do with fixing the gas pipes underneath the ground. They had finished that job now and they had left some barriers behind .In the barriers where three holes, all the barriers where stacked up on one another.My children cheared me to get in the holes and climb back out , the owner wouldn't mind as he is a freind of mine.So i climbed in, and i really wanted to come out as i am that type of person so as i went to lift my self out , it felt like something had clicked in my neck and i couldn't climb! I was screaming to my husband get me out get me out. But he couldn't lift me up they were stacked to high so in the end he had to push the barried of one another until i could free my self.I got in relaxed i nearly cried but i held it in , it was so painfull, i rang my mum to tell her what had happend and she said it was chest strain.NEED COMMENTS ON HOW TO HELP. soz
