Runny nose for 6 months >_>

plus one on that Swifty. Get it checked out properly for peace of mind:)

I agree with Mike you should ask your Doctor for an appointment with a specialist this is not normal and needs someone more qualified than a family GP to see you.

The terminology might be slightly different.

Ear, Nose and Throat doctors are specialists of those items only.

I did just a general search Googled Canada ENT Doctor and got this. So you can narrow it down to your area much easier.

Also an Allergist or Allergy specialist. That should also be similar.

Sometimes on this side of the lakes the ENT and allergists will have a clinic together.
Get several specialist under one roof or same area of a bigger clinic.

I agree with Mike, John, and Joan here. You really need to see a specialist/consultant about this unfortunate condition of yours. You may need to go to your doctor to get a referal. Best of luck, and I hope that you start to feel better soon.

I would go to the Ear Nose and Throat specialist first or after your medical doctor if you need a referral.

ENT will eliminate or find the major physical problems.
If and when they eliminate everything else they may then send you to an Allergist if they don't have one in house.
Some ENT's are allergists also.
Just depends.
