Dear Shikha
In Ketu bhukti Mercury antana which is from 04-02-2018 to 25-03-2018 you will get some relief.
Venus dasa is also not good for your health. In 2020 you will get relief. Like wise in all Mercury periods you would be getting relief.
As Saturn is aspecting 5th and 11th the recovery or relief would be slow. As Rahu is signifying Mars is there any surgery in the heart?
Can you tell what is the problem?
