Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain in case if you have a chronic sinus infection that is not resolving with antibiotics and nasal rinses then breathing through cucumber is not at all going to help and you need a proper well planned treatment for it.. I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like PNS VIEW X RAY of sinuses or MRI Scan can help in confirmation of cause.. In case of infection and inflammation in sinuses a long course of antibiotics after checking for bacterial sensitivity along with anti inflammatory painkiller like Ibuprofen, decongestant Oral like Pseudoephadrine and nasal spray like Xylometazoline can help.. You can also be advised Steroid nasal spray, saline nasal irrigation and steam inhalation. Do warm compresses around the nostrils.. You should avoid spicy and chilled foods and air-conditioning atmosphere..in case of still no improvement surgical drainage of sinuses or Endoscopic Sinus surgery will be advised. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
