Red eyes and Bartonella exposure

Hi- new to the board here! 2 years ago I was diagnosed with Lyme and Babesia. Took the antibiotics and was a fairly uneventful and easy recovery.
about 8 weeks ago my eyes started getting very red. Went to opthomologist and gave my Zylet for bacterial infection. Didn't help so went back and did dry eye test. Said eyes were dry and to use OTC drops. Still not working. about 2 weeks ago groin and knees very very achy (like last time I had Lyme). So I looked it up and of Bartonella comes up. Went back to same infectious disease dr and they ran tests for Lyme, Bart, sjogrens, and inflammatory panel. Nurse practitioner said today all came back negative except it shows that I have been exposed to Bartonella (I also have indoor/outdoor cat) but infection is inactive. I asked if he tested for Bart 2 years ago and she said no.
So here's my concern- WHY did he not test for all co-infections last time??? And is it possible I really DO have Bartonella but test is showing negative? I plan to call and speak to dr on Monday but curious as to what others think!
I really feel the red eyes and achy joints are systemic. Have not worn my contacts for 8 weeks now!!

I'm confused as well. I've signed up to the patient portal to hopefully view all the results (but it's not activated yet). That's what she said- that test shows you've been exposed to Bartonella but the infection is inactive.... What does that mean?? It seems too coincidental to me to have the red eyes and aches and hear them mention Bart...
Last time I did I had Mepron for the Babesia and doxy for Lyme. It was just one round of whatever was the standard (few weeks if I remember correctly).
