My bad doctor story:
DC, from a young age, had a noticeable weakness in his left leg. I finally made an appointment with a pediatric orthopedist, waiting 4 months out to be seen. I ALWAYS do my research on doctors and this one seemed like the best one...female, good schools, specialty in legs and feet. She examined him for maybe 10 minutes at the most, said he was fine, and when I questioned the leg weakness she said put him in soccer and that would take care of things.
A parent wants to hear there's no problem, but in the back of my mind I was still worried. This was a kid who couldn't jump with both feel off the ground when he was 2, and couldn't pull his body weight up on one leg when climbing stairs (he'd favor the weak leg by climbing one step at time, with both feet on the step in between). When I noticed this at age 4 I started working with him on it.
At the next ped visit I mentioned what the ortho had said along with my ongoing concerns. The ped immediately wrote out papers to have a PT evaluation done. Night and day difference with the ortho, as the evaluation was two sessions, one hour each. He was given normed tests and was found to be as low as 5th% in some areas. The PT found he had overall muscle weakness (low tone), extra stretchy ligaments that weren't supporting his joints, very poor core strength, the weakness in the leg, etc, etc. Basically from top to bottom he was having issues that the ortho completely missed. 5 years of weeky PT visits later, he was able to run and jump with the best of them. So many things he didn't do I hadn't noticed until he started doing them. Anyway, that's my story.
