Lower tract infections â These include cystitis (bladder infection) and urethritis (infection of the urethra). Lower urinary tract infections commonly are caused by intestinal bacteria, which enter and contaminate the urinary tract from below, usually by spreading from the skin to the urethra and then to the bladder.
And again, in Rheumatoid Arthritis, the onset is almost always symmetrical. Later in the development of the Rheumatoid Arthritis, the sounds can change to creaking, as in a knee; clicking, especially in the neck; or grinding, in ball joints like shoulders.
Rheumatoid arthritis. For juvenile rheumatoid arthritis, see juvenile idiopathic arthritis. Rheumatoid arthritis (RA) is a long-term autoimmune disorder that primarily affects joints. It typically results in warm, swollen, and painful joints. Pain and stiffness often worsen following rest. Most commonly, the wrist and hands are involved, with the same joints typically involved on both sides of the body.
