Long-term night-time breathing difficulty for 7-8 years, especially needing daily nasal drops like Nasogest, may be due to chronic nasal blockage such as Allergic rhinitis, sinusitis, or even a deviated septum. Continuous use of decongestant drops can actually worsen blockage over time, so it?s important to stop unsupervised use and switch to safer options like saline sprays or prescribed steroid sprays. Please consult an ENT specialist (as advised) for proper evaluation and long-term treatment rather than relying on daily drops.
