German Chancellor Angela Merkel said Wednesday she was “working through” a series of strange attacks of the shakes that first hit in mid-June and struck for the third time earlier in the day.

She insisted she was fine and that “just as it happened one day, so it will disappear.”

Merkel visibly shook back and forth and looked uncomfortable as she watched a military ceremony marking the arrival of visiting Finnish Prime Minister Antti Rinne, who stood by her side.

“I am fine,” Merkel told a news conference after Wednesday’s meeting with Rinne.

After the first shaking episode, when she met visiting Ukrainian President Volodymyr Zelenskiy on June 18, Merkel said she felt better after drinking some water.

“I have recently said that I am working through what happened during the military honors with President Zelenskiy,” she said.

“This process is clearly not finished yet but there is progress and I must live with this for a while but I am very well and you don’t need to worry about me,” she continued.

“I believe that just as it happened one day, so it will disappear. Otherwise I am convinced that I am quite capable” of doing her job.

Merkel’s office has given no explanation for the shaking episodes, prompting speculation in German media about the cause.

The chancellor, 64, has no history of serious health issues.

She was also seen shaking on June 27 when she met German President Frank-Walter Steinmeier, but her spokesman said she was fine and she later went ahead with her planned trip to Japan for a G20 summit.

A government official told Reuters at the time that that was more a psychological issue as she tried desperately to avoid a repeat.
