What you need to know now to manage your condition tomorrow
When you’re living with psoriasis, the itch and pain of raw, inflamed skin is bad enough. But as you’ve likely been told, there are multiple ways this disease can progress. For one in three people with psoriasis, skin itch and discomfort are only the beginning of the story; the condition can develop into psoriatic arthritis (PsA), leading to joint pain as well. But just because progression is possible doesn’t mean you’re a sitting duck for worsening symptoms. We asked top dermatologists to answer common questions about psoriasis progression and what can be done to stay one step ahead of this disease.

How Bad Can It Get?
Like other chronic, inflammatory, autoimmune diseases, psoriasis is unpredictable and varies person to person. Some people have mild psoriasis and remain stable for many years, while others may develop more severe disease with serious consequences in a short amount of time. The exact causes of psoriasis are unclear, but it involves an overactive immune system that can impact the entire body. According to the Journal of Drugs in Dermatology, people with uncontrolled psoriasis have high levels of inflammation-causing proteins found not just in the skin, but also in the blood, causing inflammation throughout the body. Untreated, the prolonged inflammation can affect other organs including the heart, liver, kidneys, and intestines, as well as joints, muscles and eyes.
What Are My Odds of Developing Psoriatic Arthritis?
“Psoriatic arthritis affects over 25% of people with skin psoriasis and can develop years after the skin involvement shows up,” explains Kate Edwards, M.D., a board-certified dermatologist at Westlake Dermatology in San Antonio, TX.
While anyone with psoriasis can develop psoriatic arthritis, those with nail and scalp involvement should especially be on the lookout, as those types are closely linked with PsA. “Nail psoriasis can present as small irregular pits in the nails, oil spots, splitting, and thickening of the nail,” says Dr. Edwards. Early psoriasis treatment with advanced medications like biologic therapies may help prevent the development of psoriatic arthritis. “These are injections administered at home every one to three months that target a specific part of the psoriasis pathway, treating the condition from within,” Dr. Edwards explains. Since biologics decrease inflammation in the whole body, they can often prevent the development of joint involvement when initiated early enough, she says.
How Do You Evaluate Whether or Not My Treatment Is Working?
If you have psoriasis, you will hopefully be seeing your primary care physician or dermatologist regularly. Staying in contact with your provider is one of the best ways to stay on top of your disease. If you are not seeing an improvement in your psoriasis symptoms after three to six months of treatment, it is time to talk to your provider about your other treatment options, according to the National Psoriasis Foundation.
More specifically, your provider should be working with you to reduce the severity of your psoriasis so that it covers 1% or less of your body within three months after starting a treatment. You should also let your provider know if you have worsening side effects from the treatment or any new symptoms. If you do need to change treatment, you won’t be alone. In one study of those living with psoriatic disease, over half discontinued their original treatment before 12 months.
Should I Worry About Aching Joints?
If your psoriasis develops into psoriatic arthritis, early treatment is mission critical. According to the Johns Hopkins Arthritis Center, the earlier the treatment for PsA, the more likely you can prevent serious damage later.
But sore joints can happen for a variety of reasons, and it can be hard to tell if your aches are related to psoriasis, or just a normal part of life. Only your doctor will know for sure, but if you are experiencing any of these symptoms, you should make an appointment to see you provider and have things checked out:
Inflammation where the tendons connect to the bone, especially on the bottoms of the feet, the Achilles' tendons, and where ligaments attach to the ribs, spine, and pelvis
Inflammation or swelling of an entire finger or toe
Pain in your neck, lower back, or sacroiliac joints
Swelling, pain, or stiffness in any joint
Why Does My Psoriasis Come and Go?
There is no cure for psoriasis, but it is possible to put it on pause. That time when the disease is quiet is called remission. When the disease and its symptoms are reactivated, this is called a flare in the condition. A flare in psoriasis can happen for both unknown and known reasons including the exposure of certain triggers such as an extreme change in weather, medication becoming ineffective, or an increase in your stress levels.
Some experts believe that even when psoriasis is in remission and is without symptoms, there is still a molecular change to the healed skin that creates a sort of inflammatory memory where the psoriasis occurred which may make it easier to become inflamed again.
Can Psoriasis Affect My Eyes?
Uncontrolled inflammation related to psoriasis can also impact your eyes. Complications affecting the eyes such as lesions of the eyelids, uveitis, and conjunctivitis can all be associated with psoriasis. These eye related conditions occur in 10% to 12% of those with psoriasis.
According to a review in Experimental and Therapeutic Medicine, certain psoriasis treatments, including disease modifying antirheumatic medications, phototherapy, and some biologic medications can also cause eye changes. The most common eye change associated with psoriasis is dry eye syndrome (keratoconjunctivitis sicca) which occurs in about one out of five patients. There doesn’t seem to be an association between the severity of psoriasis and eye changes, which means that for anyone living with psoriasis, regular eye examinations are a must.
Why Do Some Meds Work for Some People but Not Others?
If your psoriasis symptoms are progressing, it’s natural to wonder what other people are taking that’s keeping their skin in remission. What works for them should work for you, right? Unfortunately, it’s not as easy as that, says Michele Green, M.D., a board-certified New York City dermatologist at Northwell’s Lenox Hill Hospital in New York City. There are several reasons why a psoriasis medication that works for one person might not work for another, including variations in the disease itself, individual differences in immune system dysfunction, and how the body processes the medication, Dr. Green explains.
Psoriasis is an immune-mediated disease, meaning an overactive immune system causes it. According to Dr. Green, “The specific pathways and cytokines, the proteins that signal between cells involved in the immune response can vary between individuals, even if they have the same type of psoriasis,” she says. “Medication targeting a particular pathway may be highly effective for someone with a strong involvement in that pathway, but less so for someone whose immune response is driven by a different pathway.”
Dr. Green says it’s important to remember that psoriasis is not a single, uniform condition. “There are various types, including plaque psoriasis, guttate psoriasis, inverse psoriasis, and pustular psoriasis, each with distinct characteristics and potentially requiring different treatment approaches,” she says. “The severity of psoriasis can also vary significantly, ranging from mild to severe. A medication that is effective for mild psoriasis may not be sufficient for severe cases.” Even within a specific type of psoriasis, the underlying immune system mechanisms might differ slightly from person to person, influencing treatment response.
Medications are also processed by the body differently in each person. Factors such as age, weight, kidney and liver function, and other medications can influence how a drug is absorbed, distributed, metabolized, and excreted, Dr. Green notes. “Some individuals may metabolize a drug more quickly, resulting in lower blood levels and reduced effectiveness, while others may metabolize it more slowly, potentially leading to increased side effects,” she adds. Drug interactions with other medications can also impact treatment outcomes.
That’s why it is essential to consult a dermatologist and receive a proper diagnosis to treat the condition specifically tailored to you, rather than relying on medication prescribed for others.
Finding the Right Team
Psoriasis care often begins with your primary care provider. If your condition worsens or other symptoms show up, it’s important that you add more specialized providers to your medical team including a dermatologist and if your joints are involved, a rheumatologist. Either of these specialists will then be able to refer you to other medical professionals such as a physical therapist, orthopaedist, or an ophthalmologist who are experienced with psoriatic disease. The National Psoriasis Foundation maintains a health care provider directory that may help you build a great team. You can’t always prevent psoriasis progression, but the more steps you take now to stay on top of your symptoms, the better your odds of slowing its advancement.
