vishal bhai, welcome to RF and i hope u enjoy ur stay here.
Thanx to Bro.Zenzero, the sweetest heart. This kukke temple seems the best choice..(Subrahmanya/Kumaara is the lord over snakes)..in case if u can't make it to karnataka, ther's another place very close to Tirupathi, called
ShreeKaaLahasti(ancient temple of Lord Shiva), within the main premises u have a Raahu-Ketu temple too, which has been like 'THE place' for remedying Kaalasarpadosha (all planets falling between rahu and ketu in one's horoscope), famous among both Tamilians and Telugus..

we hope u'll find Shri Pt. Balaram soon..meanwhile u may start meditating either on Raahu & ketu or on their over-lords(Adhi-Devata) DurgaJi & GaneshJi,respectively ( with their shlokas or mantras)
donating grains/gems/metals pertaining to Raahu & ketu too may tonedown the effects of Kaalasarpa.
best regards Bhai..and plz don't forget to let us know when u finally done something about it. satsantaanapraaptirastu.
