Is there a relationship between sinus infection and nosebleed?
1. Dryness of the mucosal lining. This is often caused by the relatively low humidity in the air we breathe in. This is especially so during winter seasons when the air is exceptionally dry. 2. Nose picking. This is a bad habit formed when children are at a young age. Since our nose produces nasal mucus naturally, dried mucus formed tends to stick on to the mucosal lining. Nosebleed occurs when the blood vessels rupture as a result of the nail of the nose-picker puncturing these fragile vessels. 3. Injury to the nose. 4. Bleeding caused by tumors (cancerous and non-cancerous). Is nosebleed a sinus infection symptom? The answer is No. Nosebleed has never been a symptom of sinus infection. Sinus infection is caused by inflammation of the nasal mucosal lining causing it to produce more mucus than necessary. However, medication used to treat an acute sinus infection such as decongestants may cause over drying of the nasal mucosal lining in the sinuses causing them to be more prone to bleed
