One day "strained back" comes suddenly, and the execution time is , I think, less than half second.
I am afraid that I am now "smoothy back" so called, that the executive time seems to be more than 48 hours.
The pain become worser day by day, and I cannot walk normally with the hard back pain.
One of the reason might be my age, but basically the execution condition is determined by amount of work and their difficulties.
The sequences are followings.
(Step.1) The backache comes.
(Step.2) I wake up by the pain when I roll over in my sleep.
(Step.3) I drink alcohol.
(Step.4) I take a sleeping tablet.
(Step.5) I go to the office without enough sleeping.
(Step.6) I don't feel refresh and the backache become worse.
During this process, my mind become collapse soon.
-----
I know well that, if I am knocked down, a project will also be knocked down. and final everybody is going unhappy.
The important thing is not to endure the pain, but have a bravery to shout "pain!", "hard!" and "impossible" in your office. After all, your bravery will save all of your colleague.
This time, I had to use the above methods.
I know that it is clunky.
