Welcome to the forum!!!
This place is a great learning resource! It helped me seek out Lyme testing.
The low grade fever is good. The high temp really helps to kill all the little booggers! Take some tylenol if femp over 102 though.
The GI issues are pretty common. The diet your on is really good. You should have your LLMD do food allergy, gluten sensitivity, yeast, parasite and bacteria(GI) testing. Most of us have some sort of food sensitivities and all need to be on probiotics.
Read the Burrascano report that will be suggesed to you by the forum moderator. It's super helpful!
Good luck with your treatment!!
