There are some wonderful departments at CHOP, but we have not had good experiences. When DD8 was about a month old, I called dermatology to get an appointment for a rather rapidly growing (benign) vascular tumor. They told me they weren't taking new patients and they had much worse cases than hers. We went elsewhere.
Bottom line, if you think there might be an issue, have another doctor take a look. If you don't like CHOP, try elsewhere.
I don't know the details of your son's case, but DD15 has a friend that has joints that flex too far (not sure what the condition is called). It has resulted in a lot of sports injuries. Better to look into it early on and err on the side of caution.
