Hi Thank you for asking HCM. I have gone through your query. Your problem can be most likely due to sinusitis. Purulent inflammation of sinus will give such bad smell and discharge. You should get a local examination by ENT specialist to rule out the condition. Swabs should be taken for culture and sensitivity also. Antibiotic therapy and local nasal decongestant drops or spray will be helpful. If that is not helping then X ray of paranasal sinus should be done. Puncture and drainage of sinus should be done if necessary. Recurrent sinusitis can be due to low immunity and vitamin deficiency. Taking chewable vitamin C is helpful also. Hope this may help you. Let me know if anything not clear. Thanks.
