My intuition was questioned

I was a healthy kid growing up and played sports. When I went to my pediatrician at the time for an annual physical I pointed out a slight change I noticed in my first two knuckles on both hands. When the doctor didn’t listen and was adamant that nothing seemed peculiar, I still didn’t believe her mainly because I had started to do some research and it all made sense. I was sent home with it’s “nothing, just growing pains” and a signed form to take to school stating I was healthy.
