I agree with Ree. Getting a second opinion from a Lyme specialist is what I would do. I see you live in Wisconsin, which is a big Lyme hot spot.
Also if you search/google for --
llmd wisconsin
-- you will get a lot of hits. As I recall, the medical establishment in WI is not favorable to broadminded Lyme docs, who are as Ree notes sometimes called by us patients as Lyme Literate MDs, or LLMDs, but it's not an official title and the docs don't call themselves that.
It may take some digging to find an LLMD in your area, and if I had to drive some hours to do so, I would. It's not an infection that goes away by itself, and the medical profession is in serious denial.
Let us know how you do, okay? We're usually hanging around here ...

I am not medically trained, but to my knowledge it's possible 14 days of Doxycycline was not long enough to eradicate the infection. The tests for Lyme Disease are not 100% accurate. If you are having symptoms, you may want to see a physician who is knowledgable about Lyme Disease (referred to as a LLMD). If you google "Lyme Disease Association" and go to their website, I believe they have a referral function to locate a LLMD.
