Have you changed anything diet wise recently.
I ask because it took us 2.5yrs to work out that Dd2's awful eczema was caused by dairy.
She was on a prescription formula for reflux as a bub and weaned off it onto regular formula at 9mths & then onto cows milk at 12mths.
Looking back it was 6wks after starting on regular formula we saw a gp for eczema.
She now drinks oat milk & can tolerate a small amount of dairy like cheese or small amount of yogurt.
Her eczema has gone from plaguing her legs and torse to non existent
