Hi,
The itchiness may suggest a dermatitis or a fungal infection. A nummular eczema or dermatitis may be a differential here. Based on your post, the rash appears to be round or circular. The term nummular means coinlike." The disorder is recurrent and chronic, and may appear at any age, although it is most common in people in their 60's. Nummular dermatitis does not appear to be a genetic condition, is not related to food allergies, and is not contagious. The coin-shaped patches can affect any part of the body, but the legs and buttocks are the most common areas. Flare-ups are associated with dry skin, so the winter season is a particularly bad time for those with this condition."

Have you had this assessed before? I suggest that you have this initially assessed by your physician so that you may be prescribed appropriate medications.
Inform your parents or guardian about this so they may be able to help set an appointment with your physician.
Thanks for posting Vanessa. I don't have have any history of insect or tick bite. Triggers that would seem to aggravate the condition is scratching it. I have no idea of the cause of the condition and that is one of my big dilemmas.
And I have no known allergies in all of my life, I'm 15 years old.
Hope that somewhat helped. :-)
Hi.
At this point , the differentials will be a vascular or inflammatory reaction. A nummular eczema or dermatitis, a fungal infection , urticaria, erythema multiforme, annular or gyrate erythemas and erythema chronica migrans are to be considered.
Have you any history of insect or tick bites?
You have mentioned that these occur in a period of weeks? Would you be able to point out possible triggers that seem to aggravate or cause the condition?
Do you have any known allergies?
