You are not the problem! You are being an amazing mother and your son is so lucky to have you. These tick borne/parasite diseases are so frustrating. I've only been dealing with this for 6 months and I already feel it's too much. You sound like you've seen everyone, so probably familiar with all of these- but in any case it's been a few years since he was diagnosed, the original antibiotic protocols he had may not have included cyst busters as this is quite recent knowledge. Did he ever take Tinidazole specifically (combined with nattokwinase and enzymes) whilst on the antibiotic/parasite protocols? Rages are most associated with Bartonella and molds. I'm not sure what his developmental issues are but there is quite some research on dysbiosis in the gut with autism and other developmental disorders, so he could be predisposed to fungal growth. Take the tests with a grain of salt, not so reliable. It would be worth trying an antifungal such as Itraconazole if you haven't. Is he on varied probiotics? Activated cell wall chlorella and cholestyramine are supposed to be good to help bind. Using detox supports while killing on antibiotics/herbs? (NAC, R lipoid acid, glutathione, quercitin, reservatrol). Plenty of sunlight with D3 supplements, as well as D levels checked and supplemented. Also need a herbal blood thinner such as Hawthorne. One of the biggest factors with supplements is quality. Studies show most don't contain what they say. in my research I've found Mediherb/Standard process are the most trustworthy herbals (I have also taken some from Nutrimedix and woodland essence, just going on reputation). Pure encapsulation though expensive, are dependable. Has he had DNA analysis to check for things like methylation status, which may give you an idea which detox pathways may be compromised? Lastly diet, have/can you try an extensive elimination diet? I know that can be difficult so if not possible have you tried going grain, dairy, egg, nightshade, nut, and legume free ( ALL whole grain cereals -due to agglutinins/lectins). All the best, you are doing everything right!
