Sinusitis occurs when the lining of the sinus cavities becomes inflamed, often due to viral, bacterial, or fungal infections, allergies, or structural abnormalities in the nasal passages. This inflammation can block the normal drainage of mucus from the sinuses, leading to a buildup of fluid and pressure, which can cause symptoms such as nasal congestion, facial pain or pressure, headache, postnasal drip, and reduced sense of smell. Homeopathy treatment for sinusitis offers a holistic approach to managing these symptoms.
