My 14 year old daughter has a rash on her legs only. One is above her knee on her right leg. The size of a silver dollar.  Then ten inches above that are three, a few inches from each other, and the size of a nickel. On her left leg she has a rash on her thigh that looks more like a map. It is growing more each day, and each place is hot to touch, and betting redder.. Kind of mean looking. Have you ever heard of such. I have spent a long time researching. We havent changed washing detergent, nor soap. She is alergic to red dye, and recently drank a lot of grape drink. This is day 4 of having. It is itching really badly. But if she scratches it makes it itch worse.
Hi, As per your query, your daughter has itchy rashes on legs which is very common as dirt and moisture get trapped by your clothing and the friction that comes from sitting can cause pimple. It could be due to blockage of sebaceous glands leading to folliculitis or boils.  Need not worry. I would suggest you keep this area clean and Chat Doctor.  If the condition doesn't get better than consult a dermatologist for proper examination. The doctor will examine physically along with blood test and sample for a lab test. The doctor may prescribe immunosuppressants, antibiotics like clindamycin, anti-inflammatory or antifungal. The doctor may also prescribe benzoyl peroxide ointment.  Hope I have answered your query. Let me know if I can assist you further.
