One of the things that surprised me about ADHD was that along with all the usual traits like impulsivity, being easily distracted, and so on, a lot of us are hypersensitive.
Our physical sensitivities include more childhood colds, allergies, ear aches and asthma, which can also carry on into adulthood. As a child, I often woke up screaming in pain with yet another ear infection.
Even though my sister and I both spent our summer days in the pool, I was the one who got the ear infections. This makes sense to me now; I’m also the one who’s adopted and blessed with ADHD.
