Sick And Sour Taste In The Mouth When Swallowing Food
Sour taste in the mouth can arise due to the following things:
Poor oral hygiene / dental and oral hygiene.
Dry mouth due to dehydration (lack of fluids).
Dental and oral diseases or diseases of the upper respiratory tract, such as caries (cavities), coughing colds, sinusitis, etc.
GERD (gatroesophageal reflux disease) that causes reflux of stomach acid into the esophagus to the mouth
Side effects of certain drugs used
If the sour taste decreases when eating, this can be caused by the removal of saliva from the salivary glands to help digest food.
Are you referring to pain in the mouth or teeth or around the neck? Is the pain accompanied by sores in the mouth, cavities, enlarged tonsils, swollen lymph nodes around the neck?
Abnormalities in the teeth, gums, jaws are very likely to cause pain that radiates to the head both the forehead and the side of the temple (side of the head). This happens because of the same sensory nerves that innervate these areas.
To get rid of the complaints that you feel of course need to know in advance the underlying disease. If the disease is known, the appropriate medicine can be given. A pain can be alleviated by taking pain medication. Pain medication that is sold freely and is safe for consumption (without a doctor's prescription) for example is paracetamol. However, the pain will not completely disappear if the abnormality has not been treated (for example there are infected cavities that have not been cleaned and patched / pulled out).
Diagnosing a disease requires a direct examination with a doctor and also asks in detail the complaints that you feel.
* In the midst of the current Covid-19 outbreak, comply with prevention measures if going to a health facility. If it is not urgent or emergency, it should postpone a visit to a health facility to minimize the risk of contracting Covid-19. However, if you experience severe pain that is not relieved by self-medication, severe headache accompanied by vomiting, headache accompanied by a history of head trauma at an adjacent time, new sores in the mouth area that enlarge rapidly, severe headaches accompanied by high fever, severe headaches accompanied by a decrease in awareness or seizures, you should immediately check yourself in the nearest health facility.
Thus the explanation from me, hopefully useful.
