Throughout the year my nose is stopped up I can still breathe, and I can only smell really strong smells, what could be wrong?

Allergic rhinitis. Allergic rhinitis causes 'chronic stuffiness' throughout the year. You may be especially sensitive to indoor allergens: dust or mold. Other signs of rhinitis include decreased ability 'to smell' (anosmia), 'sinus pressure', and (clear) nasal discharge. Otc meds include zyrtec, claritin, allegra, or benedryl . Your physcian can prescribe nasal steroids (generic fluticasone) or singulair (montelukast) may help.
Nasal congestion. Allergies / chronic sinus infections can cause nasal congestion. Tonsillar/adenoid enlargement which may be due to chronic allergies may result in snoring, mouth breathing and nasal congestion as well. Based on the cause the treatment should be initiated.
