Psoriatic arthritis is a condition that is found in patients with the skin condition Psoriasis. Psoriasis causes moderate to extreme skin problems including red patches, itchiness and swelling. Roughly two percent of the population of white people has Psoriasis. Ten percent of that group forms another, more severe issue that causes inflammation in the joints as well as patches of skin.
The two combined are incredibly painful. Typically, people can develop Psoriasis at young ages and then develop arthritis in their forties and fifties. However, people with Psoriatic Arthritis do not just have Psoriasis and arthritis. Cases of Psoriatic arthritis are far more extreme and are rheumatic, systemic cases of arthritis.
