Hello!
Ergonomics is the science of designing the job, equipment, and workplace to fit the person. So I would want you to use proper positions in your daily living and also use proper bed, chairs while working and sleeping.
Also use proper foot wear.
Take care!
What do you mean by changing my ergonomics?
Hello!
The orthopedician is referring to scoliosis and this might be the reason of the concentration of pain and fatigue in your body on one side after physical exercise.
With slight scoliosis you might also try to correct the bend by changing your ergonomics and position. Also try to follow proper ergonomics in daily living to correct this.
Go for present day scans and take a proper advice from an orthopedician.
Take care!
