They CAN check it but they won't, they're more keen to prescribe you the meds to try out if you say you suspect that's what it is. Even if you go GP about it. Just saying because it's normal practise on other countries to thoroughly check before prescribing meds. I'd say it's more likely stuck wind that needs to be brought up before presuming the feed. But then again I think colic and (silent) reflux could easily be related with eachother..
Do you get bubbles in the bottle or teat, are there more bubbles being "put back" into the bottle during feeding..? That too can cause wind, even harsh wind that's a struggle to bring back up or even can cause vomiting when winding too late.
