Recommend a product called Neti Pot for allergy, sinus, cold, and congestion problems. It is basically a little hand held tea pot that comes with a saline solution. Mix a pot and pour it through each nostril, holding the other, and allow it to flow out the mouth. Do both sides. It absolutely completely clears you out and, in my instance, helped my allergies and congestion dramatically. Maybe found at Walgreens, etc. Highly recommended.
