Hi Tom L, welcome to our community!
I looked at the photo - and to me it looks like a spot in the middle with a ring around it.
Edited to add: I took another look and it's not a true bullseye, but I wouldn't take any chances.
Hard to see.
Can you take your wife to a Doctor today and ask for antibiotics?
She will need to treat until symptom free plus 4 more weeks. (minimum 6 weeks)
You can see that here (ILADS Treatment Guidelines)
www.lymenet.org/BurrGuide200810.pdfScroll down to Treatment Categories.
If they won't give her a month...get what you can.
Then - find a LLMD - call them and say it's a recent bite. They usually have waitlists...but maybe they will squeeze her in since treating now is crucial to reduce chances of it becoming a chronic infection. A LLMD is someone who knows how to treat Lyme disease - a specialist.
To find a LLMD, start a new thread titled: "looking for LLMD in/near______" and fill in the blank.
Then enable your email option so members can send you names privately. We don't post the names of our LLMD's on here - for privacy reasons.
You can also email me and i will check my list - and send you any names I have. Please state in your email where you are searching for one.
Also - you can contact ILADS:
