**4. Conclusion**

Sinusitis is a nasal disorder featured by inflammation of mucosal epithelium of sinuses. Clinical studies have published and trials have been conducted which shows that the sinusitis and rhinitis are the two crucial disorders associated with asthmatics. Sinusitis and asthma follows the same inflammatory pathways and temporal sequence of disease which confirms that their progression is manifested by common nasal disorder. Early prevention and treatment of sinusitis is of great interest I order to prevent the progression of sinusitis into asthma. Sinus headache is also one of the symptoms of the sinusitis. Ninety percent life time incidents of headache are reported. Migraine is some time mistakenly taken as sinus headache. Before treating headache it should be diagnosed clearly whether the cause of headache is primary or secondary. After knowing the sinogenic headache, treatment strategies must be followed. Most of the time sinus related headaches are associated with acute or chronic sinusitis.
