The condition is acutely severe like a sharp weapon or fire-log and is called ardhavabhedaka. The condition when severe may impair the functions of an eye or an ear.
चतुःस्नेहोत्तमा मात्रा शिरःकायविरेचनम्| नाडीस्वेदो घृतं जीर्णं बस्तिकर्मानुवासनम्||७७||
The 4 snehas (taila, ghrita, vasa and majja) in the maximum dose, kayavirechana (purgation), sirovirechana (purificatory errhines), nadisweda, 10 year old ghee, oil enemas,
poultices, shirobasti, cautery are advocated here. The management told for pratishyaya (rhinitis) and headaches as mentioned should also be employed appropriately.
[Suryavarta (headache increasing after sun-rise and in noon)] Witholding the urges, indigestion etc. leads to the vitiation of rakta and vata which in turn vitiate the mastishka (brain).
सूर्योदयेंऽशुसन्तापाद्द्रवं विष्यन्दते शनैः| ततो दिने शिरःशूलं दिनवृद्ध्या विवर्धते||८०||
Thus, affected by the vitiated rakta and vata, at sunrise due to the heat of sunrays these slowly liquefy and thereby during the day there is headache which increases with the day. At the end of the day as they solidify, the headache subsides.
