While there are a few conditions that can cause a purple hue to the skin, it is not a common symptom.
Causes of Purple Skin
- Erythema nodosum: This condition causes painful, red or purple bumps to appear on the shins. It is often associated with infections, such as strep throat, or inflammatory bowel disease.
- Purpura: This refers to a condition where small blood vessels leak, causing purple-red spots or bruises to appear on the skin. Purpura can be caused by a variety of factors, including medications, infections, and autoimmune disorders.
- Frostbite: Severe cold exposure can lead to frostbite, which causes the skin to turn white, then blue, and finally purple.
- Venous insufficiency: This condition occurs when the veins in the legs do not work properly, causing blood to pool and lead to discoloration, including a purplish hue.
- Certain medications: Some medications, such as the chemotherapy drug doxorubicin, can cause purple discoloration of the skin.
When to See a Doctor
If you notice any unusual purple discoloration of your skin, it is important to see a doctor to determine the cause. Purple skin can be a sign of a serious medical condition, and early diagnosis and treatment are important.
