Hubby stayed feel like stuffy and that yesterday and today he’s a little worse not not much,

His symptoms are

-very stuffy nose to the point that his actual nose is swollen and red on the outside and red on the face by the nose.

-he has some thick phlegm that he can feel.

-he has some nasal drainage but not out of his nose it’s going down the back of his throat.

-food does not taste the way it should some of the food is tasting the same while other foods he can taste what it is.

Little backstory on his health he is 31 yrs old he has high blood pressure, he has AFIB, he is on baby aspirin, metoprolol, lisinopril, fish oil and he takes allergy pills daily as he has really bad allergy to the point he can’t breath out his now if he forgets it.
