Psoriatic Arthritis

An autoimmune condition common in those with psoriasis or IBS-like conditions.
Causes swelling in a small joints and will normally only affect one joint.
Podiatric management with insoles, footwear advice, injections, anti-inflammatory regimens will initially help however, you should be referred to a rheumatologist and/or dermatologist for optimum management and I can assist in facilitating this.
