Psoriasis on Hands, Feet and NailsIndividuals suffering from psoriasis on the hands and feet often experience cracking, swelling and blistering. Depending on the severity of the condition, there are several treatments that can relieve psoriasis in these areas. Minor lifestyle changes can also relieve some of the discomfort of hand, feet and nail psoriasis.
Treating Psoriasis on Hands and FeetAcute flares of psoriasis on the hands and feet should be promptly and carefully treated. Traditionally, topical treatment of palm and sloe psoriasis have included tar, salicyclic acid and corticosteroids. Combinations of these three agents, rather than using them individually, seem to produce better results for individuals suffering from psoriasis on hands and feet. In recent years, many dermatologists have begun recommending the use of high quality shielding lotions alongside traditional treatments to curb some of the negative side effects of traditional psoriasis treatment. Another common treatment is calcipotriene, which can also effectively treat psoriasis on hands and feet. It is important to either use a good shielding lotion or wear protective gloves to keep the medicine from getting on sensitive parts of the body, such as the face or skin folds. A regimen that alternates calcipotriene and a strong topical corticosteroids may be helpful. In many cases, cracking, blistering and swelling accompanies flares. Consider using super glue to seal deep fissures. If you suspect you might have an allergy to super glue, you should do a patch test on your bicep first. If topical medications don’t work, your dermatologist may recommend methotrexate, cyclosporine or Soriatane (acitretin). Methotrexate can clear many cases of palm and sole psoriasis within four to six weeks. The risks of side effects from UV or phototherapy are reduced by combining low doses of oral retinoids with UVB or PUVA. The combination of low doses of oral retinoids with PUVA or UVB phototherapy is one of the most effective treatments available for palm and sole psoriasis. Special phototherapy units for palms and soles are widely available.
Pustular psoriasis on the Hands and FeetIt is common for doctors to prescribe a corticosteroid or coal tar as an initial topical treatment for pustular psoriasis. Phototherapy, oral retinoids and/or methotrexate may also be prescribed. Soriatane can also be a helpful long-term solution for pustular psoriasis. Biologic drugs may be prescribed for difficult cases
NailsIn up to 50 % of people with psoriasis and at least 80 % of people with psoriatic arthritis, nail changes will occur at some point. The most common nail problems are:
- Pitting—shallow or deep holes in the nail
- Deformation—alterations in the normal shape of the nail
- Thickening of the nail
- Onycholysis—separation of the nail from the nail bed
- Discoloration—unusual nail coloration, such as yellow-brown
Nail treatmentsBecause psoriasis affects the nail during formation, nail psoriasis is very challenging to treat. The nail bed is difficult to penetrate with topical medications. Corticosteroid injections into the nail bed have been used with varying degrees of success. In addition to topical treatments and phototherapy, other nail psoriasis treatments are available:
- Corticosteroid injections into each affected nail;
- Cosmetic repair including nail scraping and filing, nail polish, artificial nails and surgical removal.
