For fungal sinusitis, is FESS the only option? Even incase of FESS, will it re-occur again. My spouse had FESS done twice 5 to 6 years back. She tried homoepathy, and again in touch with allopathy recently (Sigulair, Syscan - seem to have some side effects).. We were advised FESS again by one doctor seeing CT-scan, the other doctor indicated FESS should not be done agian and again - not good and can damage tissues. Homeopathy doctors indicate this can be easily cured with their long term medication, but no relief though after 3-4 months. Please advise what is the best option ..
