I am a 33 year old Female. One year ago I was hit by a SUV while I was walking across the street. The vehicle hit me on the left side of my back and I fell to the pavement on the right side of my body. I have a number of painfull areas, but specifically since the accident I have had mid and low back pain . My mid back is tender to the touch, I can t sit or lay down with out a pillow behind my back because it feels like there is a bruise , even though there are no visable signs of a bruise. It is difficult to sit for more than 20 minutes and having a heating pad on my back helps to minimize the pain. I only get 2 hours of sleep each night and i believe the hours of sleep would be less if it wasn t for the heating pad which has an automatic shut off every 2 hrs. I take tylenol 2 to minimize the pain.
You should consult an orthopedic surgeon or spine specialist now. He may suggest investigations like MRI after examining. Do not neglect your symptoms. You may have disc prolapse or other pathology.
