You are actually in the Mahadasha of Rahu and the antardasha of Ketu since April 2015. The period till April 2016 is challenging on the health front. More so as you have Chander Gharan dosha in your horoscope, that is formed when Moon and Rahu are conjoined. Although there does not seem to be any major issues with your health, but it would be good to get yourself checked and take some medicines if necessary. Chances of spondylitis etc are likely and therefore it is important you take some medical advice. Regrading your job the period after October 2016 is much better. You should take whatever comes your way and once you have something in hand search for a better opportunity.
