" -Xiaolin of Xiantao consulted experts from Wuhan Ren 'an Hospital online. A: According to the situation you described, we should first consider the above symptoms caused by atrophic rhinitis. I suggest you go to the ENT hospital for examination and treatment as soon as possible. I wish you a speedy recovery. Atrophic rhinitis is a slow-developing atrophic inflammation of nasal cavity, which is characterized by atrophy of nasal mucosa, periosteum and bone. A person with severe and typical malodor is called a smelly nose. The common symptoms of atrophic rhinitis are 1 and dryness of nose and nasopharynx: this is caused by atrophy of nasal mucosa glands and decrease of secretions. 2, nasal congestion: pus scab blocking the nasal cavity can cause nasal congestion, or because the nasal mucosa is not sensitive, even if the pus scab is removed, the air is not easy to detect, mistaken for nasal congestion. 3, nasal secretions: often in a block, tubular pus scab, not easy to scoop out, forcibly scooped out dry scab, there is a small amount of nosebleeds. 4, olfactory disorder: the sense of smell declines or disappears. This is due to atrophy of mucosa in olfactory region or blockage of dry scab. 5. Exhaled stench: protein in the pus scab decomposes due to the growth of bacteria under the pus scab, resulting in foul smell, which is called smelly nose. 6, headache, dizziness: due to the atrophy of the turbinate, the nasal cavity lacks the function of temperature regulation and heat preservation, inhaling cold air to stimulate the nasal mucosa, and the stimulation of pus scab can cause headache and dizziness. & gt& gt& gt& gt& gt Bian Xiao recommended reading: What are the treatments for atrophic rhinitis?
