Arthritis

I was having a conversation with a friend and we were talking about Arthritis. I did know there are at least 100 types of arthritis.  decided to do some research and Lupus, fibromyalgia and Gout are types of Arthritis.

Arthritis (from Greek arthro-, joint + -itis, inflammation; plural: arthritides) is a form of joint disorder that involves inflammation of one or more joints.^[1][2] There are over 100 different forms of arthritis.^[3][4] The most common form of arthritis is osteoarthritis (degenerative joint disease), a result of trauma to the joint, infection of the joint, or age. Other arthritis forms are rheumatoid arthritis, psoriatic arthritis, and related autoimmune diseases. Septic arthritis is caused by joint infection.
The major complaint by individuals who have arthritis is joint pain. Pain is often a constant and may be localized to the joint affected. The pain from arthritis is due to inflammation that occurs around the joint, damage to the joint from disease, daily wear and tear of joint, muscle strains caused by forceful movements against stiff painful joints and fatigue.

Fibromyalgia syndrome affects the muscles and soft tissue. Symptoms include chronic muscle pain, fatigue, sleep problems, and painful tender points or trigger points, which can be relieved through medications.

Lupus, an autoimmune disease, happens when the immune system attacks its tissues, causing inflammation, swelling, pain, and damage. Lupus symptoms include fatigue, joint pain, fever, and a lupus rash.

Gout is a kind of arthritis caused by a buildup of uric acid crystals in the joints. Uric acid is a breakdown product of purines that are part of many foods we eat. An abnormality in handling uric acid and crystallization of these compounds in joints can cause attacks of painful arthritis, kidney stones, and blockage of the kidney filtering tubules with uric acid crystals, leading to kidney failure. Gout has the unique distinction of being one of the most frequently recorded medical illnesses throughout history.
