For future reference, if you strongly suspect something specific and you have reason to believe your doctor is wrong in dismissing your concerns, you can double-check that they're following evidence-based best practices by looking up the issue on UpToDate. For example, you can look up Lyme disease and see how it should be tested and when it shouldn't be tested (for which there are very real reasons). It requires a fee to use, but it's not much compared to healthcare costs of missing a diagnosis. If you find they're being negligent, definitely print it out and show it to them or get a second opinion.
