Do you have slip disc?

My whole life is slipping around. Wdym you are suffering from just a slip disk?

Taking care of my posture standing when its start to pain while sitting
Sitting when its start to pain while standing
Sleeping while both are not working
Always sitting with lower back support
And no extensive strain on body

I think you need surgery, or complete bed rest with meds, if it is really slip disc. Just some back pain is not slip disc.

Not sitting for long

How did u got this slip disc?

Try to not sit for long, get up and stand if you can't leave your desk due to meetings.
Adjust workspace so that you don't need to bend forward.
Adjust chair.
Use back support as needed.
Try to walk around whenever possible.
