How Can Sinus Problems, Sneezing, Rhinitis With Burning Be Treated?

okay for a while now, i would say roughly a year or so i have been experiencing sinus problems. i am 20 years old and i am a female. mostly during the day i sneeze a lot, runny nose, constantly blowing my nose. at night my nose gets very stuffy and sometimes it may even burn, which makes it very uncomfortable to sleep and i try elevating my head which sometimes helps but not really. but it gets dry at night but a runny nose at night happens too. lately ive had a few headaches, not many, but every now and then my head does hurts.
