The start of this transit is looking bad since already Janma Guru Ardhastama Sani is making your life miserable. Now Rahu joins with Jupiter is going to be another problematic aspect. You are expected to lose energy very fast and may cause dizziness.
You will also get disturbed sleep as a bonus. Make sure you take enough protein rich food and check your sugar level. Make sure your have complete coverage on medical insurance. Stay focussed on prayers and meditation.
Once Jupiter moves onto your 2nd house in Mid Aug 2016, you could see good recovery on your helath, until then take care!
