Your judgment may be that you hurt the muscles and nerves in your back during exercise. Swelling muscles will compress nerves and affect the normal circulation of blood.
If there is physical injury, the best way is to rest, let it recover gradually, and avoid permanent regret caused by re-stimulation. Your injured part is at the waist, so ice is not recommended. It is recommended to have more rest and be careful not to exercise in a hurry.
