After hurting horribly the doctor sent me for MRI's of my cervical and lumbar areas. The results state that
"C3-4 shows broad disc bulging indenting the thecal sac and narrowing the left neural foramen"
"Left foraminal narrowing"
"C4-5 level shows broad disc bulging"
"C5-6 level show disc bulge indenting the thecal sac"
"C6-7 shows a central disc protrusion and annular disc tear"
"There is diffuse straightening of the expected cervical lordosis"

"L5-S1 - broad disc bulge impinging on the thecal sac"
"L4-5 - broad disc bulge indenting the thecal sac"
"There is a straightening of the expected lumbar lordosis"
"Central disc protrusion visible at T11-12 with indenting the thecal sac"

All I can understand from this is bulging discs. I've no clue what indenting the thecal sac means, disc protrusions or annular disc tears mean to me. I was told that the foraminal narrowing indicated pinched nerves.
Please help me to understand what this means! Thanks so so much.
