Your medical records contain information about your subjective complaints, any objective findings, the doctor’s assessment, and the treatment plan. However, they usually do not contain opinion evidence as to your specific limitations or RFC. It is crucial to obtain such opinion evidence. This is because the opinions from your treating doctor, who usually knows your condition better than any other medical source, is usually afforded substantial weight. However, it is usually not helpful for a doctor to state a simple conclusion that you are disabled without stating the reasons why you are disabled (i.e., what your specific physical or mental limitations are).
