Psoriatic Arthritis, RA, and OA may share some similarities, but they each have their own unique quirks. PsA, for instance, loves to show off with its asymmetric joint inflammation, spine inflammation, and distinct small-joint inflammations in the hands and feet.
On the other hand, RA dives straight into joint issues, bringing along pain, swelling, and stiffness like an uninvited guest crashing the party. And let's not forget about OA, the seasoned superstar of arthritis, where wear and tear take center stage, causing achy joints and limited movement.
But fear not! We're here to equip you with the tools to spot the differences. From understanding the telltale signs like dactylitis (sausage-like swelling of fingers or toes) exclusive to PsA, to leveraging medical diagnostics like ultrasonography and serologic tests, we've got you covered!
