Different disorders tend to affect different number of joints. Because of this, the doctor differentiates between different causes when there is monoarticular pain (Flekosteel Review) and polyarticular pain. When several joints are affected, some disorders more often affect the same joint on both sides of the body (for example, both knees or both hands) than others.
This is called symmetric arthritis. Also, in some disorders, an acute arthritis crisis remains in the same joints throughout the duration of the outbreak. In other cases, arthritis moves from one joint to another (migratory arthritis).
In the evaluation of joint pain, the doctor first tries to decide whether the pain is caused by an exclusively joint disorder or if a serious disease affecting the whole body is treated (Flekosteel). Serious systemic disorders may require specific and immediate treatment. The following information can help you decide if a doctor’s evaluation is necessary and what to expect during the assessment.
If the joints are inflamed, the doctor usually puts a needle into the joint to take a sample of the joint fluid for analysis (a procedure called arthrocentesis). The doctor usually anesthetizes the area before taking the sample, so the patient experiences little or no pain during the procedure. Generally, joint fluid cultures are done to see if an infection exists. The joint fluid is studied under a microscope for crystals, which would indicate gout or related disorders. The number of white blood cells (leukocytes) determines if the joint is inflamed.
