Could there be a connection between ra and tarsal sinus syndrome?

Hi Libby. While trauma is the primary cause of Sinus Tarsi Syndrome, inflammatory conditions, like RA, are also known causes. Issues and causes of problems with the tarsal sinus are often difficult to diagnose. Your doctor should be able to provide more information and may employ a variety of techniques and tests to diagnose through a process of elimination. Best, Richard (RheumatoidArthritis.net Team)
