Hello and welcome to HCM forum,
I would like to inform you that the white line on the inside of your cheek is from cheek biting
, it is not an infection.
The white dots are opening of glands are are normal,
If the blood reports show no infection then we can rely on the reports, you need not worry.Dry mouth
and chapped lips
can be from nutritional deficiencies(vit. B and C),
I will recommend you to take multivitamins for a month atleast and check for the signs and symptoms to subside.
You should be using chap stick for dry lips and drink lots of water,
Do not worry , you are not suffering from any viral infection.
I hope this answer was useful,
I wish you good health,
