Why Am I Stiff After Sitting? Causes, Remedies & When to Get Help
You sit down at your desk, in your car, or on the couch. Maybe you spend an hour—or several hours—in the same position. Then you stand up and notice that your hips, back, knees, or legs feel stiff and tight.
Rheumatoid arthritis (RA) is a chronic, inflammatory autoimmune disorder that primarily targets the joints but can also impact other systems in the body. It affects people of all ages, often developing between the ages of 30 and 60. Unlike osteoarthritis, which results from wear and tear on the joints over time, RA causes the immune system to mistakenly attack the lining of the joints, leading to painful swelling, stiffness, and long-term joint damage if not properly managed.
