Itchy Nose and Sneezing: Allergies with Systemic Impact
Though commonly dismissed, constant itching, sneezing, and runny nose are not just nuisances—they are strong indicators of allergic rhinitis, which, if untreated, can develop into more serious conditions such as asthma, sinusitis, or sleep apnea.
Allergic reactions also strain the immune system, leading to fatigue, headaches, and poor concentration. Long-term exposure to allergens like dust mites, pollen, or pet dander can worsen respiratory and dermatological health.
Crusting and Dryness: Autoimmune and Skin Disorders
Nasal dryness and scabbing or crusting may seem minor but could be a signal of conditions such as:
- Sjogren’s syndrome
- Lupus
- Sarcoidosis
- Atrophic rhinitis
When accompanied by mouth dryness, joint pain, or fatigue, these symptoms should prompt a deeper investigation. Infections such as leprosy and tuberculosis can also affect the nasal lining and cause crusting.
