Could be a gastroesophageal reflux
Hi...Thank you for consulting in Health Care magic.
As you say it always comes during his sleep, it implies that he is getting this choking
sensation while in lying down position. This history usually fits
into a gastroesophageal reflux (GER). Whenever there is a reflux the acid irritates the upper airway, they feel like choking and clear the throat with cough
and seem to get better. I have a few questions for you -
1. Have you observed this after a heavy dinner with spicy food or oily food?
2. Is there any family history of acid peptic disease
I considered the possibility of a functional disorder
keeping in mind his age, but it is unlikely as it wakes him up from sleep.
I suggest you to see your pediatrician
with this tip and later if need be, a pediatric gastroenterologist.
Meanwhile you can try head end elevation of the bed and during the attack try some over the counter antacids.
Hope my answer was helpful for you. I am happy to help any time. Further clarifications and consultations on Health care magic are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
