Mine came back gradually. I am trying a new procedure that is supposed to last 2-3 years. They use a scope to make sure they get the exact nerve(s) that they need too. I will see how that works out.
My pain comes back gradually, but I have talked with other patients in the same practice, with the same symptoms, procedures, etc., and some said their pain comes back all at once. Some were like me, where the pain comes back over period of 7-10 days on average. I guess there is no way to tell whic category you fall in until it starts to stop working. I think it's better when it returns gradually. it buys me some time to get another procedure booked before the pain is "off the charts".
give the detail about radiofrequency lesioning
