8. Blood Spots (Purpura)
Red or purple spots on the skin, known as purpura, result from burst blood vessels, pooling blood under the skin or in the mouth. While not always problematic, widespread blood spots may signal an underlying medical issue, such as a blood clotting disorder.
To diagnose the cause, a healthcare provider conducts a physical exam and orders blood tests, including a platelet count assessment. Treatment for purpura may involve steroid prescriptions, and if platelet counts are low, intravenous medications may be necessary.
9. Swimmer’s Itch (Cercarial Dermatitis)
Swimmer’s itch, or cercarial dermatitis, causes itchy red spots after swimming in water contaminated with schistosome parasites. These parasites exist in both freshwater and saltwater.
The rash within a day of exposure but isn’t contagious. Treatment involves topical steroids, oral antihistamines for symptoms, and antibiotics if the infection persists.
10. Psoriasis
Red spots may stem from psoriasis, an immune disorder triggered by stress, meds, or injury. Identified by itchy, red plaques, often on elbows and knees. Diagnosis involves visual inspection or skin biopsy.
Treatment varies, including topical steroids, immune suppressants, and UV therapy. Relief methods include cold compresses, moisturizers, and oatmeal baths to alleviate itching.
