Hello, this is Dr. David. I have read your question and I'm ready to help.
the whistling sound from your nose most likely is from sinus congestion and mucous congestion in your nose
the cigarettes are not helping
allergies or sinus congestion or chronic sinusitis
can cause mucous to build up in your sinuses and nose, and this can cause narrowing of your nasal airways and cause whistling.
that is good you are trying to quit smoking
you should talk to your doctor about help to quit smoking
you can also use over the counter nicotine gums and patches which can help
prescription chantix and wellbutrin can also help you quit smoking.
you might benefit from allergy medications like allegra or claritin or zyrtec and steroid nasal sprays like nasocort if you have allergies causing sinus congestion and runny nose
let me know if you have questions.
