Usually, nasal allergies are due to climatic changes. The humidity in the air rises, resulting in the nasal passage becoming dry and vulnerable to infections. This infection leads to swelling and prevents the mucus from draining properly, which causes pressure and pain called a sinus. The symptoms are nasal congestion, loss of smell, dripping of mucus from the nose into the throat, green nasal discharge, cough, fever, fatigue, bad breath or unpleasant taste in the mouth, and tenderness under the eyes or on the bridge of the nose. If untreated, it spreads to the coverings of the brain and the spinal cord causing swelling called meningitis or brain abscess.
The causes of brain abscess are:
- When an infection occurs in another part of the skull, such as the ear, a dental abscess spreads directly into the brain.
- If the infection spreads from another part of the body, such as pneumonia, to the brain via blood.
- When a severe head injury occurs, a crack opens the skull, allowing bacteria or fungi into the brain.
The symptoms of brain abscess are:
- Headache occurs mostly in severe conditions that cannot be controlled with painkillers, and the pain is located in a single section of the head.
- The patient suffers from confusion and irritability.
- The nerve functions include muscle weakness, slurred speech, or sometimes paralysis on one side of the body.
- High temperature.
- Sick feeling.
- Being sick.
- Stiff neck.
- Vision changes also occur, such as blurred vision, greying or double vision(as the abscess creates pressure on the optic nerve).
When the infection spreads to brain tissues, it’s called Encephalitis and shows the common symptoms of headache, fever, or weakness. Still, in severe conditions, this results in confusion, hallucinations, seizures, difficulty in speaking, paralysis, and sometimes loss of consciousness.
Bronchitis and pneumonia are caused by the infection of lower respiratory organs showing the symptoms of cough and chest congestion.
