A Canadian member at Mount Everest Base Camp developed severe sciatica, with pain radiating down his left leg that left him unable to walk, sit, or lie down comfortably despite medication. After limited relief from treatment at the Base Camp clinic, Global Rescue medical personnel arranged an evacuation to a hospital in Lukla, where he was diagnosed with left sciatica and admitted overnight. Following physician recommendations, he was further evacuated to a facility equipped for specialist evaluation and imaging. An MRI revealed disc bulges at L4-L5 and L5-S1 compressing the left S1 nerve root, confirming a prolapsed intervertebral disc. He was admitted for additional care, improved with treatment, and was later discharged on oral medication.
