I have a deviated septum with enlarged turbinates & use afrin-type sprays off and on. Since late October, my nose has become more stuffy than usual so I have used the spray more often and have not taken more than 1 spray within any 24 hour period. I have taken the sptay in each of the past 3 days, usually around dinner time, to make eating easier and sleeping through the night possible. However, when I wake up the next morning, my left nostril quickly becomes very congested and I am unable to clear it up. Could this be rebound congestion?
