I am a stewardess. I have been working on the high-speed rail. Now my legs are always shaking after work. What's this feeling?

I am a flight attendant, and I always work in high-speed railway station. Now my legs always shake after work, which is the most obvious sign of sub-health. At the same time, we should go to the hospital for a comprehensive examination, and do a good job in cardiovascular and cerebrovascular examination to see if there are any problems and potential disease factors.
