I m suffering from allergic rhinitis for many years. My main suffering is due to persistent nasal congestion, usually on my right nose. I m also having Deviated Nasal Septum. Having problems with sleeping and concentration for long time due this. I have tried corticosteroid sprays, Antihistamine, Montelukast tablets, saline solutions, Immunotherapy, even homeopathic treatments but nothing worked to improve my condition. Please help me to cure my ailments.
