Burning sensation that radiates up from the stomach to the chest and throat is known as heartburn, that is caused due to acid reflux, or, backing up of stomach contain to the esophagus and throat.
These are symptoms of GERD.
GERD is a condition that predispose patients to the development of chronic sinusitis.
Abnormal swelling of the nasal and sinus membranes causes them to produce thick abnormal mucus.
This thick mucus can drain into the back of your throat, leading to post-nasal drip.
The sensation of post-nasal drip is most prominent in the mornings.
If you experience frequent backflows of stomach juices, up to your throat, you can have symptoms of difficulty swallowing, hoarseness, lump-in-the-throat sensation, chronic cough and throat clearing, and mucus build-up in the throat, like post-nasal drip.
Sometimes, the symptoms of GERD can mimic some of the symptoms of sinusitis.
The sensation of post-nasal drainage and the need to clear your throat constantly may be due to post-nasal drainage, but, may also be due to GERD, or, the both conditions can be present (GERD predisposing for chronic sinusitis).
A sinus headache may create pain behind, above and between the eyes and in the ears as well as a constant feeling of pounding in your face and head.
Remember, that chronic sinusitis can lead to case of ear infection.
