Unfortunately, both psoriasis and psoriatic arthritis are chronic diseases that will worsen over time. There may be times when the pain subsides or flares. Joint swelling, stiffness and pain (in any part of the body and of any severity) are the primary symptoms of psoriatic arthritis.
The most common symptoms associated with psoriatic arthritis are as follows: swollen toes and fingers (individuals may also develop deformities and swelling in the feet and hands before experiencing joint symptoms; foot pain (particularly where ligaments and tendons attach to bones, such as in the Achilles and sole of the foot); and back pain (spondylitis – which causes inflammation of the joints between vertebrae - may occur in the lower back.)
If an individual has psoriasis, it is important that he or she tell a physician if joint pain develops. Psoriatic arthritis may develop suddenly or gradually, but if left untreated, it may severely damage the joints.
