Suggest Treatment For Immobility And Leg Pain After Heart Attacks

Hi I am Dhananjay ,my father had 3 heart attacks in two years consecutively. Their age is 70 years. After hospitalization, they are not able to walk properly and they are having tremendous pain in their legs. We have done Angiography for them and we are ready for the angioplasty, but just worrying since they are aged, and after surgery, would they be ok?



Now could you please suggest some home remedy that we can do for their legs to stop the pain for the time being?
