You may experience the following effects after radiofrequency ablation (RFA):
- Leg numbness: If you have any leg numbness, walk only with assistance. This should only last a few hours and is due to the local anesthesia given during the procedure.
- Mild back discomfort: This may occur when the local anesthetic wears off and usually lasts two or three days. Apply ice to the area the day of the procedure and moist heat the day after the procedure if the discomfort persists. You may also use your usual pain medications.
