7 month old tugging on ear. Should I go to the dr.

He's had a cold and seemed to be getting over it in his own. He still coughs but it's only about 4x the whole day and I no longer have to suck boogers out of his nose. He seems so much better but suddenly started tugging on his ear yesterday. He isn't crabby. He's still super happy. Can I ride this out or should I take him to the dr. Ftm. No bashing. 🤷🏽‍♀️
