Members of Parliament in Singapore lead busy lives and can work for up to 18 hours a day, reported Shin Min Daily News.
Health Minister Khaw Boon Wan is no exception.
He spends his days attending meetings and conducting discussions with healthcare staff to understand their views and recommendations on healthcare policies.
Besides meetings, Mr Khaw makes time to read - in detail - policy papers and proposals to ensure that quality healthcare is made accessible to Singaporeans.
Official overseas trips are also part of his portfolio as a minister. However, sometimes they can take a toll on his health.
Sharing his work experience on his blog last Friday, Mr Khaw wrote: "I am here in Jiangsu for the annual bilateral cooperation council meeting. Winter has come early; it is supposed to be autumn but it was cold, chilly and foggy in Suzhou, Wuxi.
"Probably because of the winter chill, I developed a "frozen shoulder" on my right arm: could not lift the arm and brush my teeth firmly. Emailing is painful and I end up typing standing up. Even putting on a shirt is quite an operation and I have to learn to use more of my left arm.
"It is especially painful at night and sleep is less pleasant. I can now relate better to the sufferings of those with stroke disabilities."
Mr Khaw has since sought Tui Na - a Traditional Chinese Medicine style of massage - and is recovering well.
Readers and Singaporeans have expressed their concern for Mr Khaw's condition.
Some have emailed him while others have approached him during his HDB flat visiting rounds to ask after him.
Mr Khaw wrote: "I have just finished visiting two HDB blocks in Sembawang. Many residents asked me: "How's your arm?". I am very touched by their concern.
"I thanked them and said that after 2 tui-na sessions I had recovered about 75% before I left Shanghai yesterday. However, last night, the soreness returned which interrupted my sleep and I had to take a panadol and pasted a "tokuhon plaster" on my arm. I think the 5 hour flight on the plane must have caused some aggravation.
"I got up this morning feeling much better but I knew that I have not fully recovered and would have to consult a tui-na physician, or a physiotherapist, to complete the treatment.
"The residents' concerns are warm and touching. They make community service meaningful and totally satisfying!"
