<s>[INST] How does arthritis feel? [/INST] Arthritis usually causes stiffness pain and fatigue. The severity varies from person to person and even from day to day. In some people only a few joints are affected and the impact may be small. In other people the entire body system may be affected.The joints of the body are the site of much of the action in arthritis. Many types of arthritis show signs of joint inflammation: swelling, stiffness, tenderness, redness or warmth. These joint symptoms may be accompanied by weight loss, fever or weakness.When these symptoms last for more than two weeks, inflammatory arthritis such as rheumatoid arthritis may be the cause. Joint inflammation may also be caused by infection which can lead to septic arthritis. Degenerative joint disease (osteoarthritis) is the most common type of arthritis; joint inflammation is not a prominent feature of this condition. While normal joints can support a vast amount of use, mechanical abnormalities of a joint make it susceptible to degeneration.

It is healthy for you to keep active and move your joints. If you do not move a joint regularly, the muscles around it weaken and/or become tight. The joint can stiffen or even freeze. When you do try to move the joint and muscles hurt because they have been still for so long.Many things affect how your joints and muscles feel. Pain may be caused by swelling, joint damage, muscle tightness or spasm. Muscles hurt after doing exercise or activities you aren't used to; sometimes when the joint is damaged simple activities stress the joint.When your joints are inflamed or damaged, you need to take certain precautions as you do all your daily activities. Your doctor or therapist can teach you exercises and the correct use of heat and cold to decrease pain. You can also learn how to use your body with the least stress to your joints for less pain, easier movement and even more energy.Arthritis can make it hard to do the movements you rely on every day for work or taking care of your family.
