Hello doctor. after i stepped into the shower, i felt a sting on my right thigh then it began to itch. when i was done showering both my thigh were red, i figured it's because i was scrathing and now i have purple dots all over my thighs, like a rash?

Insect bite: Were you able to identify what bit you? Few bites require medical attention. If it was a black widow spider or a scorpion, it will require medical attention. Otherwise, use an ice pack to reduce the inflammation and itch. Apply calamine or other anti-itch lotion and keep the area clean and dry. If you see spreading redness outward from the bite site, you may need to see a Dr.
