Could you have spinal cord injury if you do not feel any pain, or do not feel any difficult doing any other work?

Sounds unlikely: If no weakness, no history of trauma, no infection, no tumor, no numbness or loss of sensation. No pain.No bowel or bladder dysfunction. Seems unlikely.Someone may have a congenital anomaly that has no functional impact. However if any of the above symptoms are positive that screams see a doctor. No signs or symptoms speaks to using your judgement and asking why this question is considered.
