NOTHING HELPS THE ITCH
I had the same problem, trying to find the cause of the itch. An allergist tested and found several food allergies that I wasn't aware of. If you haven't already done so maybe that will help.
Have u tried piriton it's a anti allergy relief x
There are over the counter products which can help but each person is different and each 'type' of eczema reacts differently to different ingredients/products. You really need to be your own guinea pig (so -to-speak). I've found that what I bathe with is just as important or even more so to long term skin health than creams or prescription meds for moisturizing. Cleanse with emollients NOT soap in cooler water. Try this for cleansing....
