<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, I have been experiencing joint pain and stiffness for a while now. I consulted a friend and he told me it could be rheumatoid arthritis.  <response>: I see, well we need to confirm this diagnosis with some medical tests. We will start with a complete blood count and some hematologic tests. We will also do a lipid panel and a hemoglobin A1c measurement test. We will perform a complete physical skin exam, and if necessary, an MRI may also be required. Physical therapy exercises could also be very helpful in managing your symptoms.
