I'm 24. I'm suffering from cold on daily basis from last 6 years which results in body ache, heavy eyes and not able to work on computer during office hours. I've taken homeopathic, Ayurveda and allopathic treatments but not relieved a bit. X-rays and investigations done which says I've Mild DNS with bilateral maxillary sinusitis. My present condition is that I'm not able to survive without having a tablet (levocetirizine montelukast or allegra) alternate day. I' ve consulted many ENT specialists. ENT doctor says that you have to take a tablet (Telekast-L) daily lifetime. Please suggest I am in much problem as after taking the medicine I feel vey drowsiness and low immunity. Thanks.
