Hi, has anyone had experience of branchial fistulas?
My newborn has a tiny hole at the base of her throat, to one side. On googling, I found that its most likely a branchial fistula, one of those weird human anomalies that are formed very early on in pregnancy and usually disappear. Something to do with gills (?!). It can be an opening that leads directly into the throat or to an internal organ 
It wasn't picked up on at the hospital and neither the community midwife or the health visitor have noticed it. Is it a "something-nothing" i should just let alone or should I see the GP about it?
Any advice, personal experience or more info would be much appreciated.
