As hospitals and clinics remained closed for a fourth day, the patients had no other option but to travel to India for emergency treatment, officials said.
The doctors are striking in order to press the authorities to address demands of leading orthopaedic surgeon Govinda K C, who is on the fast unto death since January 11.
Govinda, a senior professor at the Institution of Medicine (IoM), is staging the strike to protest appointment of Shashi Sharma as the dean of the institute.
All medical services have been affected at the government and some private hospitals across Nepal due to the indefinite strike.
