Nail psoriasis has three primary symptoms, points out theAmerican Academy of Dermatology Association(AAD).

These include nail pitting, separation, and white discoloration.

You may also see a thin line of blood under your fingernails or toenails.

Some of these symptoms may also indicate a nail infection, warns the AAD.

Address the root cause of your problem

Psoriasis isn’t the only cause of nail pitting.

However, if you do have an underlying condition, you’ll likely experience other symptoms as well.

Reactive arthritis, for example, also causes joint pain and inflammation.

Conjunctivitis andlower back painare common symptoms, too.

Another common cause of nail pitting is eczema, notes WebMD.

Generally, this symptom tends to affect people who haveeczema on their hands and feet.

The only way to reduce nail pitting is to address the root cause of your problem.

Psoriasis, for instance, requires a different treatment than eczema orreactive arthritis.

Let your healthcare provider know about your symptoms so he can point you in the right direction.

Meanwhile, skip manicures and cut your nails short to prevent further damage.
