Re: MRI results
Welcome to the board. As I hope you realize, members are not formally trained medical professionals, so please keep that in mind as you read. Members share experience and knowledge gained through experience.
That being said, just so you have a general idea of what the radiology report reveals, to summarize, you have a disc located between the thoracic 12 (which is the bottom thoracic) vertebra and the first lumbar vertebra that has herniated. The disc material is pressing out in such a way that it is compressing the right antero lateral aspect of the dural sac.
The dural sac is the membrane that surrounds the central canal. Since the nerves travel through the central canal, this compression can result in nerve pain for the patient.
The disc is the softer cushioning that is located between each pair of vertebrae. Due to wear and tear or injury, the disc can expand or it can break open. When this opens some of the disc can leak out and push up against a spinal nerve that is located nearby. When this happens, the patient feels pain, either in the low back or it can radiate out into a limb. In the case of a lumbar disc, it will affect the hip and/or leg region. With the T12-L1 pain is usually located in the groin and inguinal region, and inner side of thigh.
You can read about it at the sister site to Healthboards:
Depending on how badly a nerve is being compressed, the doctor may recommend letting the disc heal on its own, or he/she might recommend surgery.
You might want to look online under "herniated disc" to read further on the topic, in general. If you find some anatomy charts, it will give you a clear picture of what is going on in your back.
Your doctor will correlate the information gained from the MRI to what he/she finds upon physical exam, a basic neurologic exam and from hearing your description of your symptoms.
Good luck to you. Hope this gives you a basic idea of your issue.
