@Garz doxycycline and azithromycin, both known to kill off oxalate degrading bacteria in the microbiome? There isn't a good probiotic to replenish them and oxaluria can be a very difficult issue.
Antibiotics are not effective against persistent Lyme disease. The biofilm forming stationary phase of lyme resists all antibiotics.
Why are you not receiving treatment from your doctor? Will they not test or are the tests not confirming an infection?
I have read a number of research papers on lyme treatment. Essential oils are highly effective against stationary phase lyme and there are a number of herbs which can treat lyme & co-infections.
