Autism and urticaria

Hey everyone 

Just putting this out there as I have always thought I was different when I was younger but didn’t have an awful lot of traits. 
I had chronic urticaria from say age 20 - 24 this is an extreme allergic reaction, I had intolerance tests with no cause. I was put onto very strong medication which had to be monitored. I put it down to stress but never really thought about the connection between autism and this. I do still get this now but hardly ever but I just wondered if anyone else has had the same experience or similar?

This started a few years after I started really struggling with panic attacks, these all seem like stress factors to me (I feel so blind)

Thanks for reading
