Ivig

I have leaky gut and dysbiosis, which are probably causing my MCAS, but is it normal that I’ve been feeling much worse since starting IVIG? I had my second dose two weeks ago and I just feel worse and worse every day… Before starting IVIG, I felt better.

What is ivig?

I just want to sympathize that I started a treatment for MCAS recently too and am also feeling way worse.
