ART tests with different brands Covid negative.

Wanted to go to polyclinic to get medicine. Any way out without PRT test?

But the flu keeps flowing from the face area. Thus, cough like forever for 2 days. Tongue also pain. 
No fever.

It is a flu virus.

Injury: Head, mouth and throat. Lungs injured because of coughing. The mucus flow from the face down to the air passage that is why there is a cough. The flow is continuous. Once cough, the mucus will expel to the mouth. It is clear, plain, watery in colour.

Just see a doctor and let him diagnose lar.

Don't try to conclude that you might have this, or it might not be that, and start thinning about ART or PCR tests and what not.

There are a thousand and one illnesses, and not everybody is down with covid the moment he has a fever or a cough.

Do not listen to posts by quakes like that Sentinel, if you do not wish to leave this forum permanently, yet.
