Hi welcome to Health care magic forum. Chronic nasal obstruction
since 2years, suuggest sinusitis
, probably with D.N.S a septal defect or allergy
to some substances you are regularly using in the night like spray, deodorent, bed clothes, night dress etc. I advise you to consult an ENT surgeon for diagnosis and treat ment.
besides i advise you to follow some non medical recomendations. You will be the correct person to find the allergens you are sensitive. You observe the things after using them you get more of nasal obstruction. On taking what foods there is more nasal obstruction. On repetition you try to avoid them.
Diet recomendations as, avoid taking brinjal, fish, other sea foods, fruits and juices, as these tend to increase the allergy. take more of green leafy vegetables pulses, sprouts, milk, egg, meat, and dry fruits to build up blood and resistance. Wishing for a quick recovery, and thanks for calling.
