What Are the Symptoms of Mottled Skin?
The only symptom of mottled skin is its appearance. Beneath the top layer of skin, discoloration occurs in a net- or lace-like pattern.
The pattern is often reddish blue or purplish in appearance. The area most often affected is the legs. However, it can also develop on the limbs, torso, and buttocks.
Types of Mottled SkinThere are several types of mottled skin. The two main types are primary and secondary. Primary mottled skin typically arises due to non-severe bodily changes, including exposure to cold temperatures. Secondary is associated with medical diseases.Other types can include:Secondary livedo racemosaPhysiological variable livedoCongenital persistent livedo

Arterial Disease Types: Risk Factors, Causes, and Symptoms
What Causes Mottled Skin?
Mottled skin has various causes. It develops when blood flow to the skin is interrupted or blocked in some way. When that happens, oxygen and blood become reduced in that area, causing tension in blood vessels underneath the skin.
Secondary mottled skin is closer associated with:
These diseases will likely present with other symptoms, depending on which one a person has when they develop mottled skin.

What Medications Cause Mottled Skin?
Some medications may cause issues with blood flow within the body, leading to mottled skin. The two most notable medications are amantadine and interferon.
Amantadine (Gocovri) treats involuntary movements in Parkinson’s disease. Interferon is an immunomodulator used to treat viral infections and conditions that develop when the immune system attacks healthy cells in the body (autoimmune disease).
Other medications that can lead to mottled skin include:
These medications may not cause mottled skin in everyone that takes them, but the symptom is considered a possible side effect.
How Is Mottled Skin Treated?
The treatment for mottled skin depends on the cause. Since the appearance of mottled skin is the only symptom, and the condition can be harmless, many people are advised to avoid cold exposure to keep it at bay.
If an underlying health disorder is to blame for the mottled skin, treatments will focus on the condition that drives the symptom instead of the symptom itself. That said, some standard therapies include:
Are There Complications Associated With Mottled Skin?While mottled skin isn’t always dangerous, it can be tied to some conditions that pose severe health threats, such as strokes or other artery-blockage events. Proper diagnosis and treatment are the best way to avoid any heightened risk of severe health complications.

Are There Tests to Diagnose the Cause of Mottled Skin?
Testing for mottled skin may be complicated because of various underlying causes. For that reason, the diagnosis of the symptom is based on its appearance alone.
This helps to determine what other tests are required based on any other health disorders suspected.
Some possible testing that may be done include:
Further testing more specific to certain diseases will likely be required to get a definitive diagnosis of the cause.

You should see a healthcare provider if you notice that you have mottled skin and are unsure why or when it developed.
While it is not always a cause for concern, it can occur in people with various health disorders. Seeing a healthcare provider can ensure you’re not leaving a health condition untreated.
Summary
Mottled skin is an often-benign skin disorder that presents as net- or lace-like patterns beneath the skin. Since the blood vessels are affected, the pattern’s color will be bluish-reddish-purplish, depending on your skin tone.
While there are no other symptoms, people who have mottled skin may have an underlying health disorder that causes it to develop. The health condition causing mottled skin will present with its own symptoms alongside mottled skin, and because of that, testing to see what the cause is could be a lengthy and complicated process for some.
Contact a healthcare provider if you notice mottled skin developing on your legs or anywhere else on your body. They will be able to determine the cause and start treatment if need be.
