Hi There, Apparentely You have chronic sinusitis.Usually it is due to infection some time there might be Permanent mucosal lining which is difficult to cure. If you are having facial pain , post nasal drip, malodorous breath,headache and more pain in bending over these are symptoms of chronic sinusitis.If it is more frequent you need to make sure there are not any underlying condition , Sometime it can be confused with migraine. If the condition is chronic it is better to have bacterial, viral and fungal culture from nasal specimen. Special sinus xrays and CT scan ofsinuses will be of great help.Antibiotics are usually good only for short term relief, nasal steroid and daily nasal irrigation will really help for chronic sinusitis. Allergy medicines are shown to be ineffective for chronic sinusitis.If nothing helps you might need endoscopic sinus surgery. If you are really looking for some alternative things and need PINAS KO KATHA , let me know I will post one. Thanks
