@soxfan You're welcome. The treatments your Lyme doctor proposed are similar to what I did. As my tendons could not tolerate the Levo or similar, I treated my Bart with the combo Minocycline/Rifampin/Zithro. Those are possibly the two best combos for Bart. If the abx don't seem to work as they're supposed, it's really worth trying something to disrupt biofilm as Bart uses this for survival. It should n't take long to get rid of Bart. Best wishes.
