'Sodbrennen' (heartburn) consists of 'Sod' and 'brennen' (to burn). 'Sod' is an old word related to 'sieden' (to boil) and describes a boiling or surging movement. So the name is a figurative expression for the rising, burning feeling.
Manchmal hilft schon ein Glas Wasser gegen das Sodbrennen.
Sometimes a glass of water is enough to help with heartburn.
As a medical symptom, 'Sodbrennen' (heartburn) is treated like a substance or feeling. Therefore, it is an uncountable noun and has no plural form.
Gegen häufiges Sodbrennen sollte man einen Arzt aufsuchen.
You should see a doctor for frequent heartburn.
'Sodbrennen' (heartburn) is usually used with the verbs 'haben' (to have) or 'bekommen' (to get). If it is a chronic problem, people also say 'an Sodbrennen leiden' (to suffer from heartburn).
Gestern Abend habe ich plötzlich starkes Sodbrennen bekommen.

'Sodbrennen' is the clear and generally understood term, especially at the doctor’s office or in a pharmacy.
