10 Psoriatic Arthritis Symptoms
Psoriatic arthritis can cause pain and swelling beyond the joints. Enthesitis is inflammation of an area where a tendon or ligament connects to bone.
If it happens in the foot, it can be misdiagnosed as plantar fasciitis or heel spur, both of which tend to arise from overuse or injury. People with rheumatoid arthritis may also have foot pain, as do those with lupus, another autoimmune condition. Psoriatic arthritis can look like, or be associated with, gout, an arthritis that causes joint pain, often in the big toes.
