Hi,thank you for posting your query on health care magic. Looking at your symptoms, you are probably suffering from Allergic rhinitis (Inflammation of nose due to Allergy). Sneezing, watery nasal discharge are main symptoms of Allergy. Congestion and edema of the nose occurs due to inflammation. This leads to blockage of sinuses with retention of secretions in the sinuses leading to headache. Laboratory tests used in the diagnosis of allergic rhinitis include the following: Allergy skin tests(it would help to find out that to which substances you are Allergic), Total serum IgE, Total blood eosinophil count(IgE and Eosinophil count might be elevated in case of Allergy). It would be advisable that you undergo these tests. Perpetual allergic rhinitis is typically caused by allergens within the home but can also be caused by outdoor allergens that are present year-round.In warmer climates, grass pollen can be present throughout the year. In some climates, individuals may be symptomatic due to trees and grasses in the warmer months and molds and weeds in the winter.Common causes include the faecal matter of the house dust-mite, animal proteins from domestic pets, and industrial dusts and fumes. The management of allergic rhinitis consists of 3 major categories of treatment, (1) environmental control measures and allergen avoidance, (2) pharmacological management, and (3) immunotherapy. Environmental control measures and allergen avoidance involve both the avoidance of known allergens (substances to which you are found allergic on allergy testing) and avoidance of nonspecific, or irritant, triggers. For dust mites, covering the mattress and pillows with impermeable covers helps reduce exposure. Bed linens should be washed every 2 weeks in hot water to kill any mites present. Thorough and efficient vacuum cleaning of carpets and rugs can help. Dust mites thrive when indoor humidity is above 50%, so dehumidification, air conditioning, or both is helpful. Control measures for mold allergy focus on reduction of excessive humidity and removal of standing water. For animal allergy, complete avoidance is the best option. Exposure to smoke, strong perfumes and scents, fumes, rapid changes in temperature, and outdoor pollution can be nonspecific triggers in patients with allergic rhinitis. Consider avoidance of these situations or triggers if they seem to aggravate symptoms. You might find relief by taking following medicines : Steroid Nasal spray like Mometasone-helps against allergy and reduces inflammation, Oral Decongestant like Phenylephrine and Nasal decongestant drops like Xylometazoline-they help to decongest the nose and sinus cavity and helps in nasal blockage (if you are not suffering from Hypertension) Antihistaminic like Levocetirizine-helps against Allergy, Analgesic and Anti-inflammatory like Ibuprofen, Antipyretic like Paracetamol, in case of fever Antacid like Rantac -It helps against the increased acid formation in stomach due to the use of Analgesic and Saline nasal spray-helps to moist the nasal cavity and removal of allergen particles from nose. If you suffer from high grade fever or fever continuous for more than 2 days,pus discharge from nose,etc suggesting of secondary bacterial infection,then you might need to take oral Antibiotics after consulting an Otolaryngologist Doctor. Also do steam inhalation. Do warm saline gargles. Avoid cold food. Immunotherapy: may be considered more strongly with severe disease, poor response to other management options in which the patient is introduced to gradually increasing doses of Allergen to which the patient is known to be sensitive on Allergy testing. Hope this answers your question.I would be happy to answer if you have any follow-up questions. Take care.
