hi, thank you for your query. what your suffering from is the acute sinusitis variety which generally lasts between 3-5 weeks. but if it lasts for more than 6 weeks then you need to shift your regimen to- Medical therapy should include both a broad-spectrum antibiotic and a topical intranasal steroid to address the strong inflammatory component of this disease. Antibiotic therapy might need to be continued for 4 to 6 weeks symptoms generally subside after this period. thank you, wishing you good health
