First off I would bet that doctor was at the bottom of the class. And has a complex of being higher than anyone else who isn't one. I would suggest going to the ER and trying to get some x-rays, as there might be a blockage from eating a toy or somthin to that effect. Is he in pain or obvious pain, or just running around like a little hellion? Eats like a bird? Or at all? I know that sometimes my youngest won't eat for a day or two and that will throw off his system. Also try a Nurse Practitioner. Good luck.
