I am suffering from allergic rhinitis and sinusitis. It has been with me for a a while now, like 4 years. I constantly have a stuffy nose, constant sneezing, runny nose and watery eyes. I have taken various montelukast tablets and nasal spray (lecope m, nukast, montus etc). It helps as long as you are taking tablets and starts again when I stop taking tablets so I have to take these medicine every day and there has not been a day where I didn't have these symptoms. Is there any way I can stop this? thanks.
