You should see a doctor to be examined so that it can be determined if your current symptoms are related to your accident from 3 years ago. The treatment would depend on what is causing your symptoms. You may need testing to find out what is causing your symptoms like x-rays, CT scan, MRI, etc. Physical therapy may be helpful, depending on the diagnosis. So, see your doctor for evaluation!
