Hi Kimberly,
I've found this info on a site for you, hope this helps. I think the waiting is the worst part of it. I've spoke to my Consultants Secretary she told me I should be having my 2nd of in January (I won't hold my breath)! Unfortunately the Nerve Root Block didn't help me at all, but you might be lucky.
Nerve Root Block
A nerve root block is an injection into the sheath surrounding a nerve root in the spine to decrease your pain temporarily and to define it more precisely. The exam uses therapeutic steroid and local anesthetic (numbing medication) to decrease pain and inflammation. Pain relief from the procedure varies from minimal to long-term, depending on the specific symptoms.
You must have symptoms present for this procedure to be effective. If you are not experiencing symptoms prior to your procedure, please cancel your appointment and reschedule the exam once your symptoms have returned.
You will need a driver for your appointment. If you are unable to drive or arrange transportation, call us for assistance.
During the procedure – what to expect
You will remain awake throughout the procedure.
A radiologist will use a thin needle to place anesthetic and steroid (anti-inflammatory medication) into the nerve sheath. (There may be some discomfort from the needle, but, for most people, this is minor.)
The radiologist checks the needle position using x-ray-guidance (fluoroscopy).
Contrast material is placed into the nerve sheath to document the needle position and x-rays are taken.
During the injection, you may feel pressure or pain. The radiologist will want to know how this discomfort compares to your usual pain symptoms.
After the procedure – what to expect
Initially, you may experience numbness and/or relief from your symptoms for up to six hours after the injection.
When the anesthetic wears off, your usual symptoms may return. The steroids usually require 2-3 days to provide pain relief.
If there is no change in your pain symptoms after a week, your doctor may want to investigate other possible sources for your pain.
Possible side effects
Steroid medications may cause facial flushing, occasional low-grade fevers, hiccups, insomnia, headaches, water retention, increased appetite, increased heart rate, and abdominal cramping or bloating.
These side effects occur in only about 5% of patients and commonly disappear within 1-3 days after the injection.
Bye for now, take it easy.
