This has been bothering for sometime now. Me and my sister were diagnosed with RA around the same time 3 years ago (we were 29 and 30 years then) though there is no history of RA in the family. Mine is the severe type compared to my sister. We have another sister who is 27 now and she is perfectly healthy (touch wood) but just having my doubts if she will start showing RA symptoms when she reaches 29/30. Does any one have siblings with RA? can we get a diagnosis for RA before the onset?
