I went through my trial and had great coverage. During my permanent placement they had to go through the bottom of the tail bone because they couldn't get leads placed in correct spot. Since the leads are placed in a totally different spot, I don't expect the same coverage, but was getting pretty close. Rep tweaked the program and it felt good for a day, now it feels like I have fallen off of a ladder and had the wind knocked out of me. I can't describe it, just that uncomfortable feeling you have when you hit the ground. It is not effecting my breathing and the lungs are not the problem. Just wondered if anyone had any ideas as to what might be going on. I appreciate any advice.
