Hi L.,
Very interesting you mentioned this! I have 2 boys whom are now 4 and 2. However, when my 2 year old was 15 months, he was running with his older brother, fell, and his older brother landed on his leg. It happened while my mother was watching them, and when we returned home, he was down for a nap. When he woke up, he wouldn't touch his leg to the ground at all! My Mom mentioned the boys had fallen, but she said she thought the baby was just whiney and tired, so she put him down for a nap.
Since it was a Sunday, I took him to urgent care later that afternoon and they told me it was probably just a pulled muscle, and that they didn't see anything in the X-Ray. The next day, I too just knew something else was wrong, so I took him to our regular Pediatrician. She was very suspicious, and immediately sent us to a wonderful Orthapedic Doctor in Clarkston. He did X-Ray's and it turns out there WAS a hairline fracture on his growth plate. Though nothing was out of line and it ended up healing beautifully, I was so frustrated at the mis-diagnosis by the original Doctor's that treated him! We basically had to keep him contained for about 3 weeks, and made sure his older brother wasn't around him when they were up moving around! I have now learned that 2 boys = disaster sometimes!
If you are looking for another opinion, I had great luck with Dr. Nallamathu in Clarkston. He is young and very thorough. He didn't stop until he had an absolute diagnosis. As a Mom, that is exactly what I needed!
Hope this helps, and good luck!
S.
