I Have A Very Sore Back Mainly The Middle Of

I have a very sore back mainly the middle of my back the pain is constant. I had a sore stiff neck which has been happening often lately. This usually lasts a couple of days then comes right. It did come right then two days later I woke up with a very sore back. It is a constant pain and at times especially in the morning takes my breath away and feels like I am being crushed around my middle. The pain is a lot worse when lying down especially on my back.
