acute sinusitis should be treated with 10 days of amoxicillin and what you are having is acute on chronic sinusitis. i would suggest completing the course for next five days. continue the steaming and use saline nasal spray. do not blow your nose so hard. if the antihistamine is making your nose dry then do not use it use paracetamol for pain relief. allegra (fexofenadine) is a good medication but sometimes can cause nasal dryness. once the nasal dryness is cured you can also use nasal steroid that has fluticasone or use nasonex (mometasone) or nasacort (triamcinolone). use one spray in each nostril throughout the spring season. for further information consult an internal medicine physician online --> <link>
