About 7 months ago I was in a rear end collision. Within the first week I was experiencing back and neck pain. It has now been 7 months since the accident and I am still in severe pain especially after work throughout the day. The pain is mostly in my back in the middle of my shoulder blades. I am not sure if it is a spinal problem or a muscle/tendon problem. I am very tired of hurting and my doctor seems to not take my injuries seriously. Is this whiplash? Should I go back to the doctor?
