रक्तं पित्तसमानार्ति किञ्चिद्वाऽधिकलक्षणम् । शूलं समुदितैर्दोषैः सशोफज्वरतीव्ररुक् ॥ ७ ॥
produces earache, which has the same symptoms of that caused by Pitta, but little more in severity. Earache produced by the combination of all the doshas is accompanied with swelling, fever, severe pain,
पर्यायादुष्णशीतेच्छां जायते श्रुतिजाड्यवत् । पक्वं सितासितारक्तघनपूयप्रवाहि च ॥ ८ ॥
desire for hot and cold comforts alternately, sluggishness of hearing occurs; when ripe (after suppuration), copious quantities of white, black and red thick pus flows out.
When Vata gets localized in the sira (channels) which convey sound, the person often hears different kinds of sound without any reason. This is said to be Karna Nada.
श्लेष्मणाऽनुगतो वायुर्नादो वा समुपेक्षितः । उच्चैः कृच्छ्राच्छ्रुतिं कुर्याद्बधिरत्वं क्रमेण च ॥ १० ॥
Vata associated with Kapha and getting increased or by neglecting Karnanada gives rise to hearing of loud sounds only with difficulty and to deafness gradually.
