You should not insert any cotton wool inside the nostril as this can cause more problem with breathing.
Also there is risk of infection from that.
Sometimes the cotton wool go far inside requiring further intervention.
You can use a saline nasal drop to keep your nostrils open.
Also Oxymetazoline nasal drops will help to keep your nostrils open.
You should consider an antibiotic course to treat the sinus infection.
Please discuss with your doctor these options.
