I am not a doctor and I have only have cervical problems and surgeries in the C levels.

At C4/5 You have an annular disc (bulge?) Bulge means a type of displacement of the disc in which the fibers of the anulus fibrosus (part of the disc) remain intact but extend into the spinal canal. This is the mildest form of displacement, better to have than a tear.

The whole spine branches off into thirty-one pairs of nerve roots. These roots exit the spine on both sides through spaces (neural foramina) FORAMEN between each vertebra. Appears you have a nerve root pinched (compressed) at the exit for C4-5. This level would most likely cause neck, shoulder or arm symptoms.

Disc prolapse is a loss of height in the space. Think of it like a marshmallow (disc) between graham crackers (vertabrae) and when marshmallow gets squishy, or leaks out the sides when you put pressure or shrinks when they dry out. The crackers can then rub each other of catch a piece in between them, etc.

L5 is a big cause of sciatica. Go over to the back board there are lots of people there with lower back probs.

Good luck
