You have a doctor that suggested SCD, wow? That's great. Maybe he will also prescribe LDN for you?
I wonder if you eczema could be a result of the oats? I think oats contains gluten.
Why do you think it might be related to VSL?
As for VSL, I would suggest the packets rather than the pills, and adding slippery elm powder too.
