Hiya , i am trying to get a definitive answer , took me ages to get to a diagnosis of sero positive RA , now the consultant is saying I also have PsA .
All the literature i read states that the defining factor as to a diagnosis of PsA is that you are sero-negative .
I do have both sets of symptoms applicable to each version of Arthritis , Have a + ve RA factor , AND have recently developed Psoriasis on my legs, Lower Spine , and Buttocks ..and spreading fast .
Am on MTX and Leflu which i know are good for both types, and use Dovonex and Betnovate for the skin issue , i am just curious as how common it is to have both , as stated above , most sites including PAPAA suggest/ infer that you can't have both .:O
I never did do things by halves :O hehe
Any ideas or links to further reading that mentions having Both types of Arthritis
