If you have no other symptoms, like headache, fever, fatigue, or nausea, an
over the counter decongestant allergy medication may help you...like Claritin
D or Allegra D...always buy the generic versions of those to help save you money, because they are quite expensive for a month's supply. If that medicine doesn't help, or you have those other symptoms I mentioned, you may have a sinus infection and require an antibiotic to cure it! Good luck!
