Hello, For the past month 1/2, My 8 year old s thumb is swollen at the joint area. It s the only part of her hand that is swollen and hurts when she bends it. X-ray came back normal, no broken bones, MRI appeared to be fine as well. We recently got a series of blood test done and are waiting for results. During the same time frame, she complained of her heel hurting- it hurts the most in the morning. The pain did go away after two weeks. What do you think it could be since it s localized inflammation that haven t changed. Is it possible that it could be Juvenile Rheumatoid Arthritis? Just looking for answer...
