Rheumatoid arthritis is caused by a combination of genetic and environmental factors that can lead to an abnormal immune response and inflammation in the joints. Signs of rheumatoid arthritis include tender, warm, and swollen joints, especially in the mornings or after periods of inactivity, along with general fatigue, fever, and loss of appetite. Dr. Tanveer Bhutani at Eva Hospital has extensive experience and qualifications in treating rheumatoid arthritis and helping people live pain-free lives.
