Allergies board

It could be a couple of different things - the most likely is allergies. I'd recommend that you try taking an antihistamine (either Zyrtec or Claritin) and a decongestant (Sudafed 12 Hour) for a couple of days to see if that helps.

All of that stuff is available without a prescription at any drug or grocery store.

If you try that for a few days and it helps it's probably allergies - so you'll probably want to keep taking the antihistamine until allergy season passes.

If the antihistamines and decongestant don't help you might want to see a doctor - there's a remote chance it could be something more serious (like nasal polyps) but the fact that it shifts from side to side makes that less likely.
