Hello. Arthralgia means you have pain in your joints that is not inflammatory. There are many possible causes. If your doctor has not told you the cause yet he/she may still be exploring the cause. If your doctor is not running tests to find out more, you should pursue that with him/her. Once the cause is identified a prognosis should be able to be given to you. Hang in there.
you should test your ASO and RA factor and Uric acid ok
and you'll have your diagnosis
