I wouldn't use the spray any more than ONE time a day. Do you know if it's an infection or you are allergic? If you're allergic to something, try a pill type medication. The only thing that works for me is a prescription of Bromfenex capsules, 2 a day.
If you have an infection the sprays won't help as much as just keep doing more damage. Try and get an antibiotic that you take orally like liquid or a capsule.
