Step-by-step solution
Inflammation is a process in which the body's WBCs and the chemicals released into the blood or the affected tissue to protect us from infection and foreign substances such as bacteria and viruses. This releases of chemicals increases the blood flow to the area of injury or infection. Inflammation is characterized by redness, swollen joint that is warm to touch, joint pain, joint stiffness \& loss of joint function.
The increase number of cells and inflammatory substances within the joint causes irritation, wearing down of cartilage (cushions at the end of bones) and swelling of the joint lining. Inflammation of one or more joint results in arthritis. When there is a deposition of uric acid and crystals of sodium urates in the joints it will lead to gout arthritis. Uric acids is the end metabolism products of nitrogen containing purine nucleic acid. Gout generally affects one or two joints only. It is very painful particularly at night, and makes movement difficult. Gout generally affects great toe.
