Bad breath can be related to sinus infections or other infections involving the upper respiratory tract. Difficulty breathing through the nose, headache and nasal congestion can also accompany allergic reactions, sinus infections, or non allergic rhinitis. If you have symptoms of an upper respiratory infection that do not improve, seek the advice of your doctor.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
-
Sinusitis
Sinus infection (sinusitis) is caused by allergies, infection, and chemicals or other irritants of sinuses. Signs and symptoms include headache, fever, and facial tenderness, pressure, or pain. Treatments of sinus infections are generally with antibiotics and at times, home remedies.
-
Hay Fever
Hay fever (allergic rhinitis) is an irritation of the nose caused by pollen and is associated with the following allergic symptoms: nasal congestion, runny nose, sneezing, eye and nose itching, and tearing eyes. Avoidance of known allergens is the recommended treatment, but if this is not possible, antihistamines, decongestants, and nasal sprays may help alleviate symptoms.
-
Indoor Allergens
Indoor allergens are substances that can cause an allergic reaction in some people. Common sources of indoor allergens include dust mites, cockroaches, molds, pets, and plants. Avoiding indoor allergens is one way to reduce allergy and asthma symptoms.
-
Chronic Rhinitis
Chronic rhinitis (non allergic rhinitis) causes runny nose, sneezing, nasal itching and congestion. Post-nasal drip is drainage of mucus from the sinuses into the throat. Treatment includes over-the-counter (OTC) medications.
