I am an Emergency Room Pediatrician (a physician that takes care of children that come to the ER). AMA.
Proof will be provided soon as i don't have anything accessible at the moment that actually proves that i'm really a doctor (a.k.a Sphygmomanometer, Stethoscope and coat in my locker at the hospital, and Degree on a wall at my office).
Ask me anything. I can give advice, but i can't do a full checkup on you/your kid online. For emergency medical care, head for the nearest hospital.
EDIT: K guys, 00:00 on my country, i have a shift tomorrow, if i have time i'll get the proofs ready and i need to get some sleep. Cya!
EDIT 2: Lunch break, will answer some simple questions that came up.
Btw my English is not so good (foreigner) but i'll do my best.
