So sorry to read that you are suffering from this. Are you detoxing (dry skin brushing, detox baths with Epsom salts and hydrogen peroxide, foot baths, etc.)? When bacteria die off they leave over toxins. If toxins are not eliminated they can cause havoc.
When I was sick with chronic lyme I suffered from the toxin Ammonia that caused joint pain, brain fog, fatigue, etc. What helped me was taking a remedy called Neuro-Antitox CNS/PNS which targeted the ammonia in my body and brain (it crosses the BBB).
Some people can actually smell the ammonia from their body. It kind of smells like cat urine..
Hope this helps,
12 years well ~ used Dr. Jernigan's protocol from his book about
Biological Medicine (used Borrelogen, Microbojen and Neuro-Antitox).
I still detox even though healed and drink Green Vibrance. I come back to help others for others helped me when I was sick. Pay it forward!
