Thanks to both of you for your advice. I decided to wait it out a little longer to see if it would just clear up on its own, but it's been another week or so now and if anything things have gotten worse. Antibiotics & time hasn't healed it so I'm going to see an ENT asap to get the help & reassurance I need.

Thank you both again, & I hope you're both doing well.
If this does turn out to be anything serious I'm glad that I'm already signed up here for further advice/support.
