Rheumatoid Arthritis
Unexplained pains and aches could be triggered by rheumatoid arthritis. This is another autoimmune disorder that causes the immune system to mistakenly attack body cells. It would trigger swelling and inflammation of joints. People of all age groups can be at risk. In the early stages, it is hard to diagnose because symptoms tend to mimic those of other conditions. Sometimes, you can only feel a sense of stiffness or aches in your joints, which can be caused by many things. A blood test could detect inflammation, but a precise diagnosis of rheumatoid arthritis requires a comprehensive physical exam and medical history. [9]
