Sir My Name Is Rahul. I Am A Student Of

Sir my name is Rahul. I am a student of class 12. I have been suffering from swelling In the nasal passage ( probably swelling of nasal turbinates)for more than a month. Initially I thought it is just a minor cold so I used to decongestants like nasivion to get temporary relief. But with the decongestant spray I get a relief of 8-9 hrs. I went to doctor who prescribed me an anti allergic med and fluticasone spray.the med that I am currently taking are azithromycin tablets, sterio 8, and ebastine tablets, fluticasone propionate spray. But these med doesn't seem to work much.. Sir I'm also preparing for various competitive exams so its becoming very difficult for me concentrate as I'm having difficulty in breathing without a decongestant (oxymetazoline). Sir, I request you to plz prescribe me some med so that I can get instant relief.. I will be really thankful to you..
Regards
Rahul
