Eczema is a bacterial disease that manifests under your skin.
Garlic is the best natural ointment that kills bacteria. Don't eat raw garlic but rather mix it in your meal. If you have to eat raw, use small quantities.
In addition, it might have something to do with your central nerve system so coconut oil replacement in your food instead of cooking oil or any other industrial oil should solve your problems in a matter of weeks.
Garlic has antibacterial and antibiotics so this is best to eat.raw and also to scrub in those area that affected
This is tried and tested for my family hope will also be on you
