Please consult a doctor, not an internet forum.
Not always the best advice. It was my web browsing, and the literature I printed and brought to him, that convinced a doctor that my step-daughter had EDS. He was only vaguely aware of the condition before that. I was convinced she had it after about five minutes of surfing. After looking the facts over, he was compelled to agree. Without me doing prior research, it's hard to say how much longer a diagnosis would have taken.
It's a big medical world. No one doctor can know everything.
I did consult a doctor, he told me not to worry about it. However, it seems a bit beyond the normal childhood food issues, but not too serious yet.
