Shabby, I have several urinary issues also and for the past 15 years or so I thought the burning upon urination was from tight pelvic muscles but now you've changed my whole thought process.
Maybe the Lyme is the real cause. I do know I was bit by a tick about 20 years ago so it's quite possible. I was bit again summer of 2011 and now my urine has a strong odor and microscopic blood not to mention a host of other symptoms non-urinary since the second bite. Such a weird disease how it manifests.
