Joint pain is the sensation of discomfort or soreness in a joint or joints of the body. Joints are the spaces or areas where two or more bones meet, such as the hip, knee, shoulder, elbow and ankle. Joint pain can occur with or without movement and can be severe enough to limit movement. People may describe joint pain as discomfort, inflammation, increased warmth or burning, soreness, stiffness, or pain.
The joints allow our bones to move. They are made up of cartilage, ligaments, tendons, bursas (fluid-filled sacs that help cushion the joint), and the synovial membrane (lining of the joint capsule that secretes synovial fluid to lubricate the joint). Any of the structures in a joint can become irritated or inflamed in response to a variety of mild to serious diseases, disorders or conditions.

Bleeding can range in severity from a simple bruise to blood in the urine, stool, or sputum (mucus and phlegm). Bleeding can occur from any body part including the digestive tract, blood vessels, eyes, brain, and joints. Bleeding from the surface of the body, such as from a puncture wound, is often promptly identified and treated; whereas, internal bleeding is much more difficult to track and diagnose.
People who take blood-thinning medication or who have a bleeding disorder, such as hemophilia, are at risk for severe and prolonged bleeding because their blood does not clot properly. However, these types of conditions usually can be well managed when you adhere to your overall treatment plan prescribed by your doctor. Severe bleeding and suspected internal bleeding need a prompt professional medical diagnosis.
