Hello there,,,,well from the history of symptoms you gave it seems ....repetative movements cause you pain in elbow and hand.
I would like to know ....weather small joints of your finger and wrist pain too?
Is the pain only in right elbow and hand or both hands?
Also do you feel the pain is more in cold climate as compared to hot climate?
Also a positive ANA test could suggest presence of Rheumtoid Arthritis....however a positive ana test does not always mean you have the disease.
Next Steps
do resort back for furthur queries.
regards & take care.
