Cobie's arm

Gosh, here we go again! Well it started Thursday morning ( Jan. 7) Cobie woke up complaining his arm hurt. I just assumed it was from sleeping on it weird and we went along our merry way. Friday he went to a friends house and Saturday when I picked him up, he was still complaining. He is now unable to extend his arm out past a 90 degree angle. I notice that it is a little swollen, but not bad. He is having trouble putting on clothes and feeding himself , and is now running a low grade fever, so I make an appointment first thing Monday morning to see his peditrician. She doesn't like the look of it and sends us to get an Xray done. The results are faxed back to her office and the nurse calls to say it is either a dislocated elbow or a fluid filled sack that is infected. She doesn't feel qualified enough to make the distinction so she makes an appointment to see an orthopedic surgeon. Hopefully we will be able to get in there before the week is out.
Where did this come from?? The only thing we can think of is he fell on that same arm last month, maybe even more than a month ago, diving for a football and landing on the concrete. His elbow (same one) was scraped up quite a bit, and left a scar (mainly because he picked at it non stop), but I couldn't believe it wasn't worse than it was. This incident was probably what started it. So, NO MORE football at our house, first it was Logan jumping up in the air to catch a football in the yard and landing on a huge pine tree root and slicing his knee wide open , almost requiring surgery.. he still needed physical therapy! Not to mention the HUGE scar across his knee.. more like indention really. Sports.. not a fan!
