What is a foraminal disc herniation?!
Question: This would be easiest to explain if I could show you a model of the spine. Since I can't, so far as I know, post an image with my answer, it will help you, as you read this, to look at an image or model of the spine.
Each vertebra has an arch on the back side. These arches form a tunnel, through which the spinal cord travels. The spinal cord ands at about L1, and the spinal nerves that extend further down the spinal canal are called the cauda equina.
The nerves come out from the spinal canal on either side, between the arches, through openings called foramina.
Sometimes, when there is a rupture (herniation) of an intervertebral disc, the extruded (herniated) disc material presses on the nerve where it goes through the foramin, and this is a foraminal disc herniation.
Nerve root compressions can cause impairment of motor and/or sensory nerves, resulting sometimes in pain and often in partial or complete loss of movement and/or feeling in the portion of the body to which the nerve fibers go from that spinal cord level.

its when the disc in you spine is pushing towards your spinal cord which results in numbness and weakness in your body at that spinal segment..the disc pushes your nerves
Foraminal Herniated Disc
A foraminal disc herniation is located to the side of the spinal canal underneath the nerve and is in the bony tunnel in which the nerve exits the spine. After the nerve leaves the spine, it travels into the arm to perform its intended function. Compression of the nerve in the foramen (bony tunnel) causes symptoms in one arm in the distribution of that particular nerve.
