Hello! My brother has been recently diagnosed juvenile rheumatoid arthritis. He used to be healthy although he always had bad appetite and my mother had usually forced him to eat. Otherwise he had no health problems. We were in shock when he got ill. There is no one in our family with arthritis, not even our grandmother who is seventy. I don’t understand how this could have happened. What causes juvenile rheumatoid arthritis?
