2. What the Red Dots Could Be (Including Schamberg Disease)
These dots may be petechiae—tiny red or purple marks caused by small blood vessels breaking beneath the skin. They can result from minor pressure or from medical conditions affecting blood vessels or platelets.
One possible explanation is Schamberg disease, a mild form of capillaritis that often affects the lower legs. It causes reddish-brown discoloration from leaking capillaries. Though chronic, it’s generally harmless and manageable. Other possibilities include allergies, infections, or inflammatory skin issues.
3. Simple Checks You Can Do at Home
You can gently press on a spot with a finger or clear glass. If it fades, the cause may be vascular rather than bleeding-related. Track the size, number, and distribution of the dots over time.
Pay attention to symptoms like itching, pain, or skin texture changes. Taking well-lit, dated photos can help you notice progression and provide useful information for a doctor later.
