Livedo reticularis is thought to be due to spasms of the blood vessels or an abnormality of the circulation near the skin surface. It makes the skin, usually on the legs, look mottled and purplish, in sort of a netlike pattern with distinct borders. Sometimes livedo reticularis is simply the result of being chilled. But it may be a symptom of a serious underlying condition, such as vascular disease. And it may occur as a side effect of certain medications.
When to see a doctor
The condition usually clears up without treatment. See your doctor in the following situations:
The discolored, mottled skin doesn't go away with warming
The discolored, mottled skin is accompanied by other signs and symptoms that concern you
Painful nodules develop in the affected skin
Ulcers develop in the affected skin
You also have peripheral vascular diseases.
This is a new development and you are known to have lupus erythematosus or other connective tissue diseases.
I have this on both my legs and I haven't been exposed to cold air. I've seen a dermatologist and had a biopsy done and the results came back normal. Which is incorrect, this is not normal and something is wrong. It's been a year and my legs won't clear up and I refuse to wear shorts due to embarrassment
why do my legs do this if its cold or hot
This happens to my pregnant daughter when she goes in the sun.
he's dead lmao
My dad says he has mottled skin every once in a while. He also has heart problems but can’t see a heart doctor because they are booked until November. Should he go to the ER?
