back home, again

We seen a different doctor this time at Children's and this one thinks he has something called apophysitis of the hip. Simply put it means he has overused his hip joint and severely pulled a ligament. It could have been caused by the intense stretching that he does playing first base since he refuses to step off the base and literally will do the splits to catch a ball.
I have read some about it and it seems some people are just more prone to this type of injury and it can be reoccurring (such as 6 months ago).
The cure for this is rest which is so ironic seeing how non-rest is what got him into this position to start with. He is to take it easy for 2 weeks while continuing his current anti-inflammatory medicine. Sounds simple enough except this child only rests when he is asleep! How am I to keep him from being active for 14 days??
I really do hope they have finally solved this mystery and he can eventually return to normal. I still am not completely forgetting about the possibility of Lupus given the family history and other symptoms he has, it is just being put on the back burner for now while we focus on resting.
