Activists in Myanmar are calling for civil disobedience.
Many hospital medics are either stopping work or continuing but wearing symbols of defiance in simmering anger over the suppression of Myanmar's short-lived democracy.
Protesting medical staff say they are pushing for the release of Ms Suu Kyi.
They are wearing red, or black, ribbons and pictured giving the three-fingered salute familiar from the Hunger Games movies and used by demonstrators last year in Thailand.
Online, many changed their social media profile pictures to one of just the colour red.
"Now young people in Myanmar... have digital power, we have digital devices and we have digital space so this is the only platform for us" Yangon Youth Network founder Thinzar Shunlei told AFP.
A Facebook group has been set up to co-ordinate the disobedience campaign.
But there have been few signs of major protest. On Tuesday night, drivers honked their horns in the main city, Yangon (also known as Rangoon), and residents banged cooking pots.
Myanmar has been mainly calm following the coup, with troops on patrol and a night-time curfew in force.
There have also been demonstrations in support of the military - one attracted 3,000 people, AP news agency reports.
Hundreds of MPs were also detained by the military but were told on Tuesday they could leave their guest houses in the capital.
Among them is Zin Mar Aung, an NLD MP who spent 11 years in jail on political charges under military dictatorship.
She told BBC Burmese she had now been given 24 hours to leave the MPs' compound.
"Currently the situation is very very tough and challenging," she said. "Under the military coup it's very dangerous if we speak out about what will be our next steps... only thing that I can say is that the MPs of parliament will stand with our people and vote."
