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.
What is rheumatoid arthritis? Arthritis is a general term that describes inflammation in joints. Rheumatoid arthritis is a type of chronic (ongoing) arthritis (resulting in pain and swelling) that occurs generally in joints on both sides of the body (such as hands, wrists, and knees). This symmetric multiple joint involvement helps distinguish rheumatoid arthritis from other types of arthritis.
