They are protesting against the decision of the hospital's governing body to sack its chief P Venugopal for allegedly violating a code of conduct.
The 1,500-bed hospital in the capital, Delhi, is funded by the government.
Patients, mainly from poor families, have the worst affected by the strike.
"I have been coming here for radiotherapy for the last 15 days. Now the strike has started and I am being denied treatment," Ram Swarup, who is suffering from a brain tumour, was quoted saying by the Press Trust Of India.
"I do not know how many days I can survive if treatment is discontinued."
Some reports said that a 35-year-old man, suffering from a heart problem, had died after he was refused treatment at the hospital on Thursday.
There are about 1,200 doctors at the hospital.
