<s>[INST] A 72y/o female presents with progressively worsening pain and stiffness of her joints. She reports decreased range of motion and redness and swelling in the joints. She reports symptoms occur in the same joints on both sides of the body and are worse when she first wakes up [/INST] Hi, thank-you for providing the brief history. A thorough clinical examination is advised. As this related to more of a morning stiffness and swelling this sounds to me more like a RA. As per the age of 72 I can only figure out this. Having a past medical history into consideration while making diagnosis should provide some more inputs. For confirming RA the blood test has to be performed along with thorough clinical examination Regards Jay In Chat Doctor.  </s>
