Question: My 22 month old had acid reflux when he was born. He now seems to be having the same issue. Screaming when laying down n waking up screaming. Not like a temper tantrum, like he screamed as a baby with acid reflux, like horrible pain. I kept his dinner light tonight but he grabbed his chest n said "owie, owie" over n over. I have also noticed lately his breath or burp will smell like raw meat. Does the raw meat smell mean its even worse than I think?

Not currently on any medications. Has been taking miralax.
Since he had acid reflux as a newborn we have always given him probiotics and Colic water. Since then we never had any issue. He hasn't had any invasive tests done. Our dr has been on vacation. His practice gave us another dr that told us it was just terrible 2's. We didn't believe that. He was also extremely good and independant about bed time and recently has screamed for over an hour and a half inconsolable going to bed and also waking screaming at odd times when before he had always slept through the night, after getting the reflux under control the first time.We went back and saw another dr in the practice and she had ordered an abdominal x-ray showing he had moderate constipation. We just got a urine result today that also shows a UTI. Which he will be on amoicilin for when I can go get it. He only just started rubbing his chest, and saying that it hurts.
The burp raw meat smell comes and goes for about the last 2 weeks.
I am using this as more of a second opinion since his normal dr has been on vacation and after the dr that said it was terrible 2's, we would have missed all this if we weren't persistant, knowing that there was something more going on with him.
Thank you for you opinions in this matter. I just want to make sure to get other opinions so that we don't miss anything that may be very important to his health.
