What is “Rheumatoid Arthritis”?

Rheumatoid Arthritis is a disease where the body attacks its own joints. It causes pain, swelling, and stiffness.

History of Rheumatoid Arthritis 

Rheumatoid arthritis has been known for hundreds of years. Early signs were seen in ancient skeletons. In the 1800s, doctors started studying it closely. They found that it is not just joint wear but an immune system problem. Over time, scientists discovered that the body attacks healthy tissues by mistake. This made it different from other joint diseases. Today, modern medicine uses drugs to control the immune system. Research is still going on to find better treatments and possible cures. Awareness has also improved, so people can get early diagnosis and better care.

What is “Osteoarthritis”?

Osteoarthritis is a condition where joint cartilage wears down over time. It causes pain and stiffness, mostly with age.

History of Osteoarthritis 

 Osteoarthritis is one of the oldest known joint diseases. It was seen in ancient human bones and even in animals. In early times, people thought it was just part of aging. Later, doctors found that it happens when joint cartilage slowly breaks down. In the 20th century, X-rays helped doctors see joint damage clearly. This improved diagnosis. Today, osteoarthritis is known as a “wear and tear” disease. Scientists study how lifestyle, weight, and movement affect it. Treatments now focus on pain relief, exercise, and joint care rather than cure.
