Is my husband catching a sickness or is it allergies?

So alllll day today he has been having a stuffy & runny nose, along with watery eyes.

I don’t know if he’s getting sick or not, he’s never really gotten allergies before, it’s rare if he gets allergies so I don’t know what to think.

He doesn’t have a headache, no sore throat, no cough, no body aches but his nose is constantly runny, sneezing constantly, stuffy nose, and his eyes are watery. His voice is starting to sound sick but I’m guessing it’s because of his nose.

He took an allergy pill but his nose is still stuffy & eyes are still watery and red

Can he be catching a sickness or is it allergies?
