There apparently is relief coming the way of people suffering from certain types of sinus inflammation --- in the form of a nasal spray containing capsaicin, which happens to be the main source of the "heat" in hot chili peppers! 
According to the results of an allergy research carried out by University of Cincinnati researchers – led by Jonathan Bernstein -, a nasal spray which contains Capsicum annum, an ingredient derived from hot chili peppers, could probably ease the problem of some sinus-related inflammations. 
In what was the first controlled trial to compare the use of Capsicum annum nasal spray - on a continuous, as-needed basis - and a placebo spray, relief was sought for sinus pain, sinus pressure and sinus congestion in 44 subjects suffering from non-allergic rhinitis. 
It was found that capsaicin – which is present in hot varieties of chili pepper plants of the genus Capsicum, and was approved by U. S. Food and Drug Administration as an over-the-counter topical pain relief treatment in 2009 – generated generates the sensation of spicy heat in the mouth; thereby triggering a faster onset of action or relief. 
With testers using the spray containing capsaicin having reported symptom relief an average of one minute faster than the control group, Bernstein said that the research basically concludes that the Capsicum annum nasal spray was “safe and effective on non-allergic rhinitis”!
