This could be the rash of Lyme but I think it is more likely to be a cellulitis (skin infection) from the bite. Lyme ring rashes usually have more than one pale and red circle. The treatment for Lyme is prolonged Zithromax treatment. The treatment for cellulitis can be the same or a drug that covers strep and staph. For home measures trying soaking in salt water. Use baking sodas paste on the "bites" to draw out to axons. Benedryl may help with the itch. If the rash is spreading see a doctor. If she is sicker with fever then also see the doctor. If you live in the mid or eastern states and the is getting to look like a series of rings then see the doctor for antibiotics. Best to you to get insurance and ID etc.
