It is very important for you to fill out your pain diary following the injection and bring it to follow up appointments. Once the aesthetic medical wears off the pain will likely return and you may have some increased soreness for a day or two.
What is the next step after the injection?
If you benefit from the procedure, the next step would be considering of radio frequency treatment of the medial branch nerves. This is a procedure that will provide pain relief for a longer period of time (average of one year). This will be discussed at your next appointment.

The other complications are infection, bleeding and nerve injury. These complications are minimized by stopping blood thinners, using sterile technique, and fluoroscopy for x-ray needle guidance.
