Hi....I do not know about gerd causing chest congestion
, but do know that congestion can cause gerd.
So, if u have had post nasal
drip, even if u r unaware that could have some impact on ur gerd.
U may want to
try a netti pot and do see ur ENT to
rule these issues out or treat them if u do indeed have them.
Also, check with ur GI dr to
see if u may have another issue like a hiatal hernia going on.
