think of it ur nose connected to ur eyes,ears, and ur head. and yes it is all conected and i had a sinus too but i don’t feel any sinus symptoms it only occur when it is rainy season and i when i had a sinus in the beginning i thought that my head was gonna explode and it really hurts and every time i turn my head upside down i feel the pressure and it hurts well some doctors prescribed anti-drowsey pills and forgot the other name of it well it was really effective for me but don’t try it just stick to ur doctor what he or she prescribe u the best. and others says that sinus is a forever symptom that cannot be removed because my aunt had a sinus and it is forever to her since she was in high school and she was now an college graduate and working as a recruiter agent and when her sinus appears she can’t hardly speak of cloged nose
