I just have a xray while ago.and i was diagnosed that i have mild levoscoliosis , thoracic spine.im worried about my employment .is it dangerous?

No it is not : Dangerous as a mild curve and should not restrict you i. Any employment or activity. However, since it is a left type curve, a MRI of your spine is recommended as this type of curve can be associated with a neurologic issue as a precaution.

Evaluation: Most likely everything is fine and probably within normal limits. Many such films are read with such reports. Check with your doctor.
