I suffer so bad from eczema so when i fall pregnant i end up getting it ten times worse due to hormone changes the only thing i can suggest is get a good moisturiser keep using it, it should get a little easier and a good tea tree or dandruff shampoo as these have good cooling down properties which should help itching good luck
This is my third had the same with all of them I'm nearly 30 weeks so not long left jus wade it out
I had very minor Eczema on the inside of my arms (elbow area) before pregnancy. Now at 34wks it is driving me nuts and doubled in size.
I take warm bath with oil in it (i ran out of bio oil so used canola lol still helped a lot!)
Then I just rub a lot of moisturizer on it!
