I agree that it is a good sign, however, if this still doesn't clear up our condition despite being allowed to try it, then it would mean that EC itself is a new kind of unknown membrane disorder, which would totally suck.
May I ask how his social life is doing? I got this many months during my vacation after high school grad, and I cannot imagine getting this during high school because it was a very fun time for me. I'm just about to start college but to be frank, I'm scared. There are just so many things that I/we cannot do comfortably because we are technically limited.
It's also weird that a lot of us here got this at such young ages, and there are even new sufferers as young as I am (I'm 17). I wish you were my mom, my dad and I argued about this and I really feel alone with no support in my family, but life's like that I guess haha.
I wish the best for you, your son and everyone on this forum. No one deserves this.
