procedure is pretty much like the shots except they put a thin needle in and tickle it with current to see if it is in the right place where the pain is coming from. Then for about 15 to 30 seconds feels like someone taking a magnifying glass and pointing it at one point on your back ... no real pain to it .. then for a day or two later feels like a slight sunburn .. other odd side effects .. scratch your butt and you will feel it in your lower back .. no pain just like the nd of a nerver ...I'm jumping through hoops now trying to get the insurance company to approve treatment again ... it has been over two years so they won't go right to the nerve ablation .. will make you do shots first .. I wish I would have done the nerve ablation years ago like a miracle ..
