You would have to see a homeopathic person to see what foods your body is not liking in one way or another. My daughter has eczema. No allergist will tell her it’s related to a diet, but homeopaths did and told me which food groups and foods. Good luck.
In my opinion thats pretty easy to work out yourself then, write down what foods you eat a lot, then assume these could be the one’s you are intolerant too, then eliminate them for 2 weeks to 3 months & see if anything it improves.
I’m not convinced an IgG test will tell you anymore than you can work out yourself, especially the pin prick tests that you post back to them.
