Discogram or discography is ideally an examination that evaluates if the intervertebral disc in the lower back is causing the back pain or not. The discs are spongy questions between the vertebrae or spine bones that act as the spine's shock absorbers and keep the spine flexible. When a disc gets injured due to heavy lifting or age-related deterioration, the outer layer weakens the gel-like inside and tries to squeeze it. A bulging or a ruptured disc is very painful and can press on the nerves in the spinal column and cause pain or weakness in the back. The pain can also lead to neck pain and leg pain.
Dr Sk Rajan can identify which disk is causing you discomfort during a discogram by injecting dye into the discs and viewing them on the X-ray or CT scan. The process helps them to know which disk to treat or remove surgically.
The working of a discogram
You can get some sad dictation by intravenous medication that relaxes you, and then you will lie on your stomach on the X-ray table. The doctor will numb the skin area by applying local anaesthesia on your back. The doctor will then insert a needle into the back and in the centre of the disc. They will inject dye into the disc and then remove the needle. They will also ask you to rate the discomfort level in the back or leg. Any pain caused by the injection is temporary, so you don't need to worry. The doctor might also repeat the process for other discs. You need to go through an X-ray or city scan of your injected discs after the injections. This is because the disk has tears and is damaged if the injected die has spread from the disk's centre.
Ideally, the process takes around 30 to 45 minutes, and then you can stay for observation for at least 30 minutes. After that, you can go home.
What happens after the procedure
After the procedure, you might have some pain where the needles were injected, but it will go away after some time. You can continue with your regular diet or medications instantly, but you should not drive or do any rigorous activity for at least 24 hours. You need to take it easy and return to your normal activities the next day.
A discogram is your best bet if you have any back pain that is not improved for 4 to 6 months. The physical therapy or other consecutive treatments is not working, then also the test is recommended, and the process uses the extra city scan. The discogram is not ideal for pregnant women.
