Two studies compared capsaicin with placebo . One study reported that capsaicin resulted in an improvement of overall nasal symptoms (a primary outcome ) measured on a visual analogue scale (VAS) of 0 to 10. There was a mean difference ( MD ) of - (95% confidence interval ( CI ) - to -), MD - (95% CI - to -) and MD - (95% CI - to -) at two, 12 and 36 weeks post-treatment, respectively. Another study reported that, compared to placebo , capsaicin (at 4 µg/puff) was more likely to produce overall symptom resolution (reduction in nasal blockage, sneezing/itching/coughing and nasal secretion measured with a daily record chart ) at four weeks post-treatment (a primary outcome ). The risk ratio ( RR ) was (95% CI to ).
Structural problems with the nose and sinuses may ultimately require surgical correction to cure them. This should be done only after more conservative measures have been tried and failed. Septal deviation, septal spurs, septal perforation, enlargement of the turbinates, and nasal/sinus polyps can lead to pooling of or overproduction of secretions, blockage of the normal pathways leading to chronic sinusitis, and chronic irritation. The surgery is performed by an ear-nose-throat doctor (otolaryngologist). Surgery can also enhance the delivery of nasal medications and rinses into the nasal cavities.
It can be difficult to tell the difference between a cold and hay fever. If you have hay fever, your runny nose will likely have a thin, watery discharge, and, despite the name, you will not have a fever. If you have a cold, you may have a thicker or yellowish discharge from your nose, and may have a low-grade fever. Hay fever symptoms can begin immediately after you are exposed to allergens like pollen or animal dander , and will continue as long as your exposure continues. A cold will most likely begin a day or two after exposure to the virus, and can last a few days to a week.
