What is mean by Sinus Problem? What are the signs of sinus?

1. Facial Pain or Pressure: One of the hallmark symptoms of sinusitis is pain or pressure in the face, particularly around the affected sinuses. The pain may be localized to specific areas, such as the forehead, cheeks, or around the eyes.
2. Nasal Congestion: Sinusitis often causes nasal congestion or a feeling of blockage in the nose. The congestion can make breathing through the nose difficult and may result in a stuffy or "stuffy" sensation.
3. Nasal Discharge: In addition to congestion, sinusitis can cause a discharge from the nose, which may be thick, yellow or greenish in color, and may contain mucus or pus. This is known as postnasal drip and can lead to a persistent cough.
4. Reduced Sense of Smell: Sinusitis can affect the sense of smell, leading to a decreased ability to detect odors or a loss of the sense of smell altogether. This symptom is known as anosmia.
5. Facial Tenderness: The affected sinuses may be tender to touch or pressure. Palpating or pressing on the affected areas of the face may elicit pain or discomfort.
6. Headache: Sinus headaches are commonly associated with sinusitis. The pain is typically localized around the sinuses and may worsen with bending forward or sudden movements.
7. Tooth Pain: In some cases, sinusitis can cause referred pain to the upper teeth, leading to toothache or discomfort in the dental area. This occurs due to the close proximity of the sinuses to the upper teeth roots.
8. Fatigue and Malaise: Sinusitis can cause a general feeling of fatigue, tiredness, or overall malaise. This may be attributed to the body's immune response to the infection or the disruption of sleep due to symptoms such as nasal congestion.
