Hi ShuLuv - welcome!
The rash from a tick bite isn't always a typical "bullseye " rash.
The fact that you were bit by something and have symptoms, along with imaging of your brain showing white spots on the MRI certainly is reason to look into Lyme disease as the cause.
Lyme testing is unreliable - many false negatives, unfortunately.
There are labs that specialize in tick borne testing....they are better than the standard labs.
And unless the ID Doc is Lyme literate, you will most likely be disappointed with the appointment.
With your history, and MRI, I suggest you find a LLMD for an evaluation.
We can help with that.
Start a new thread: "Looking for LLMD in/near______" and fill in the blank.
Then enable your email option so members can privately send you names. We don't post the LLMD names on here for privacy reasons.
In addition to members recommendations, you can also email me - I may have some options listed.
We encourage our new members to read through the information in the thread titled: "New to Lyme?...Start Here"
It's got a lot of useful information in it to read.
