Benefits and risks
When NICE looked at the evidence, it decided that there was enough evidence to know how well this procedure works. The 7 studies that NICE looked at involved about 4000 patients.
Generally, they showed the following benefits:
-
Pain relief, lasting at least 12 months after the procedure.
-
Improved ability to carry out everyday tasks.
The studies showed that the risks included problems after the procedure including pain, muscle tightness or spasms, and weakness. These got better over time for most people.
NICE was also told about the possible risk of damage to the tissues or blood vessels.
If you want to know more about the studies, see the guidance. Ask your health professional to explain anything you don't understand.
