Can those with medical knowledge help me out with this? I have a pertubring sinus problem i.e. itchy eyes, blocked nose, feeling groggy everyday. Thanks!

i never heard this.
try instead:Otrivin nasal spray
use Tylenol sinus for pain+congestion.if you cant take tylenol,Advil also makes a sinus medication.
When i have a very bad sinus infection,my dr gives me antibiotics for 10 days.
try also a moisturizing nasal spray its basically salty water!
i use one called sterimar,but other companies make simply saline.
spay it into the nasal passages.
