Are you chronically somewhat congested? Dark circles? If yes, read on, otherwise disregard.
"Exercise rhinitis" sounds like a load of bullshit to me. I'm guessing you've a biofilm infection. Kill it. Use a sauna every other day and every other day run a neti-pot of xylitol solution through your sinuses. Get it all the way up; turn your head upside down. You can buy xylitol at some grocery stores.
A course of tetracycline and/or erythromycin in conjunction with saunas and xylitol solution irrigation might be worth considering. The sauna gets your blood flowing through all the tissues that don't get much blood flow and can get the antibiotics to the sites where they need to do their job.
