What is right paracentral disc protrusion at T8-T9 and T7-T8?

Answer 1

This means that the spinal disc ("shock absorber" between the vertebrae) is protruding (bulging) on the left into the area where the peripheral spinal nerve leaves the spinal cord (neural foramen). If the disc compresses (impinges) the spinal nerve in the neural foramen, there can be symptoms that radiate into the extremities. If the nerve impingement is in the neck, then symptoms are usually felt in the shoulder blade area and arm. In the low back, the symptoms can be felt in the buttock and back of the thigh ("sciatica") and even the entire leg and foot.

Answer 2

When the disc protrudes backwards, it comes in the spinal canal. Here it is on the right side of the mid line. This has compromised the spinal foramen. That means, there is pressure on the spinal cord.
