Lyme Symptoms Return

Last summer I was diagnosed with Lyme disease. I had the rash (solid, not bullseye), developed chest pains, headache, neck stiffness, mild nausea. I went to an urgent care center, was given a full workup and prescribed a course of Doxycycline, which seemed to knock it out and I felt fine for awhile, but over the course of the next several months, my symptoms began to return.

I had bloodwork done that showed I have a current Lyme infection and just last week, my PCP put me on another course of antibiotics (Amoxicillin), which I am currently taking. The choice of Amox was based on the fact that my wife and I were about to head to the Caribbean for a vacation that would have made staying out of the sun impossible, and thus Doxycycline wasn't ideal. We are now back from the vacation and my symptoms have slightly improved, but I want to be sure to really knock this out this time and was hoping for advice.

Since my symptoms aren't severe, I imagine I could just complete the course of Amoxicillin and see how I feel, but I was hoping to get some input. Maybe a course of Doxycycline in addition to the Amoxicillin would be a good idea? I haven't been able to find a reliable specialist in my area yet. The only infectious disease doctor I spoke to (referred by my PCP) said he doesn't treat people with longterm Lyme disease. Sheesh.

Any advice would be appreciated!
