I'm glad to hear that you've gotten some good relief from the trial. As others have said...it's a very big thing to consider and everyone has to make the decisions that will be best for them regarding their treatment. My advice is always to do as much research as you can to get both the pros and cons of the permanent surgery and then make the decision with eyes wide open about the risks and benefits both. I personally have not chosen to pursue this course of treatment but many have and are very happy with the results. If this works for you and gives you relief then that is wonderful...just make sure you know the risks and feel they are worth it. Sometimes you have to risk the getting worse for the CHANCE to get better...and if the trial has gone well then hopefully that's a good sign for you. Take care and keep us all posted.
