Psoriasis is a chronic skin condition that causes inflammation and scaling of the skin.

There could be a connection between your husband’s psoriasis and the pain you have described. Psoriasis is not usually painful.

Still, approximately 10% of people with psoriasis develop arthritis (called psoriatic arthritis). The arthritis is more likely to develop in people whose psoriasis involves their nails, with “pitting” or small indentations. And the joint symptoms may even develop before the skin disease.

Psoriatic arthritis usually involves only a few joints. This is in contrast to rheumatoid arthritis, which usually involves far more. Also, it may involve the lower back (called sacroiliitis). And often, it includes the tendons as they travel near joints, a form of tendinitis.

Your husband’s ankle could hurt because of arthritis and the heel pain may be related to tendonitis of the Achilles tendon. Other typical features of psoriatic arthritis include stiffness that is worst in the morning, swelling and warmth around the painful areas and improvement with anti-inflammatory medicine (such as ibuprofen or naproxen).

Of course, the pain in his feet could be unrelated to psoriasis. He should review his symptoms with his doctor, and have a complete exam. This can help find whether there is a connection and to decide on the best treatment.
