Mri say small disc protrusion not touching nerves,but i'm getting mild symptoms of sciatica could it still be this?

Yes: MRI gives positional/stationary view of disc and nerve while lying down. Maybe different while standing/walking.

Sciatica: Yes, it is possible that this bulge is causing your mild sciatica. The most common cause of sciatic pain is a disc bulge or rupture. Other less common causes are spinal canal stenosis, bone spurs, and a pinched nerve root from an injury.
