Madam Sudharani
The lagna of your son is Scorpio. Lagna sub lord Rahu is in 8th house (longevity, defect etc). Rahu is conjoined with Venus (lord of 12th house – hospitals). Rahu is in the star of Mars (lord of 1st – self and 6th house – sickness) is in 5th house (Cure from ailments). Rahu as a node signifies 11th house also and its lord Mercury in 9th house (poorva punya). So blending all these, we can say that the boy has longevity. At the same time, the immunity is poor. There would be some defect and cure is indicated, because of his poorvapunya.
2nd house indicates speech. 2nd cusp sub lord Venus is in 8th house (defect) sign Gemini (airy sign). Gemini as it is 3rd in the natural zodiac, it denotes nervous system, brain etc. Venus is in the star of Rahu in 8th house. Venus is in the sub of Saturn in 3rd house (right ear). Saturn is in the star of Sun in 9th house. So there would be a defect in the right ear and nervous system. But as Venus is conjoined with Rahu (a node), it signifies 5th house (cure and relief- explained above) and 11th house ( cure and relief ). Definitely he will get relief in Venus or Rahu periods or sub periods. To confirm this the 5th house and 11th house (cure and relief) sub lord Mercury is the lord of 11th house. So he will have a cure and relief certainly. Another factor is Mercury is in a watery sign which is a mute sign.
Cure when ? Present dasa is of Mars which is upto 13-7-2025. Next comes Rahu, which is upto 13-7-2043. In Rahu dasa Rahu bhukti is upto 25-3-2028. Rahu will transit in Jupiter star. That Jupiter is the lord of 2nd and 5th house is in 2nd. So it will be good for him. The permanent cure and relief would be in respective periods. As Saturn aspect is on 5th and 11th houses, the cure will be slow.
Good Luck
