Hi Daniel,
Welcome to our community!
If you haven't already, it would be helpful for you to start with reading through the thread at the top of the forum titled,"New to Lyme?...Start here!!", as it is packed full of important information, symptom lists (as Lyme rarely occurs by itself), helpful links and pdf's, how to detox when one has these infections, a list of questions that you can ask any doctor that you are seeking treatment from and so much more.
As Deejavu suggested, please take a picture of this rash. The bulls eye rash is the skin form of Lyme disease, so if you have the bulls eye rash, you have Lyme disease. Don't wait to see if you develop symptoms though - right now is the best time for treatment. You will have the best chance at not having to deal with this later on if it's treated properly now.
According to the new (2014) ILADS (International Lyme and Associated Diseases Society) treatment guidelines:
"Recommendation 2b:
Clinicians should prescribe amoxicillin, cefuroxime or doxycy-
cline as first-line agents for the treatment of EM."
www.ilads.org/lyme/treatment-guideline.php An "EM" means erythema migrans or bulls eye rash. You can find many pictures of them online.
Can you get in to see a doctor and see if they will prescribe you some antibiotics? Please be sure to take a look at the treatment guidelines to be sure you get a high enough dose of abx. Generally 400 - 600 mgs of Doxycycline for at least 6 weeks will take care of Lyme in this stage- EM rash without symptoms.
