Re: Do I have RA?
You need a complete symptom review by your Primary Care Physician/Internal Med, Orthopedic Surgeon, Physical Therapists and possibly a Rheumatologist. There may be tests like x-rays and blood tests.
Tendinitis and bursitis can be very difficult to treat as frequently they are due to repeated overuse of a part of the body, not using the right body mechanics, etc.
