B.C.
I never heard of asthma from Tums.
I'd be skeptical about it.
It does sound like the Tums are not doing enough to help your heartburn.
I'm hypothyroid, so I'm always worried about anything going on with it.
About 10 years ago I got a feeling in my throat like there was something in it I could not swallow.
I was convinced my thyroid was growing and trying to choke me.
I went to my ENT and he scoped my throat (numbs the back of the mouth and puts a camera down the throat through the nose).
Well - my thyroid was absolutely fine.
My esophagus just above my stomach was inflamed - acid reflux - and I was feeling it in my throat way higher up than where the irritation actually was.
A month on Prilosec cleared it right up.
I think you need an acid inhibitor for awhile so you can heal up.
I think the acid reflux irritation is causing problems in surrounding areas and the Tums was not doing enough to curb the irritation.
In a round about way, what he's saying is basically correct, but not in the way you think it is.
