Praveen is doing all he can along with managing his daily work which is required to feed his family. Doctors have recommended to give his father an injection for next 3 months twice a month, this will help him extend his life and have a better life as long as he is alive.
To do this it costs INR 2.4Lacks/Injection, apart from this he has so spend approximately 80K to 90K INR for regular medicine.
There is nothing better he can do to his father; but, to do this he has to spend 6 Lacks/month ($8000 USD/month) for next 3 months.
If we all come together we will be able to achieve this with ease. The minimum that we can do is to help him to come out of this financial hardship.
